My clownfish laying eggs.

In order to breed clownfish, you will need a mated pair.  The easiest way to do this is to purchase a mated pair. Often times fish stores can order a mated pair or many online shops carry them as well.  The second way you can be sure you have a mated pair is buy two clownfish when they are young.  When clownfish are young, they are always males.  Once they have determined the dominant fish, it will change sexes into a female.  After some time, you will be be able to tell which is the female because it will always be larger.  This comes after much fighting between the two fish.

Often times the female will nip at the males tail and the male will look like he is having a seizure.  He will roll on his side and start twitching rapidly.  This is his way of saying I give up to the dominant female.  My fish took 6-8 months before the sex change was obvious.  Any species of clownfish will work.  I breed true perculas in my 150 gallon tank.  Once they start breeding they will lay eggs every 12-18 days usually on a piece of live rock.Clownfish Community A tank of at least 30 gallons is needed to keep clownfish happy.  Clownfish are not as sensitive as some other marine fish but keeping the water clean does make them more likely to spawn.  Be sure to make weekly water changes of at least 10% of the total water volume.  A good protein skimmer can make water changes less frequent.  Always check the reviews on the protein skimmer you are thinking about purchasing at Protein Skimmer Reviews.  The other tank mates (if any) must be peaceful.  Beware of putting different species of clownfish together.  They often will fight and stress each other out.  Stressed fish will not lay eggs.  Having an anemone helps to make the clownfish feel comfortable to lay eggs.  However, an anemone is not required.  A good amount of live rock with plenty of hiding places will make the fish feel more comfortable.  The lighting for the tank should be on a timer.  A timer will get the fish in the routine of sunlight and darkness.   Try to feed the fish at the same time everyday with a good mix of different kinds of frozen and flake food.  If the fish are not getting the proper vitamins and nutrients, whatever eggs they do lay will most likely be of poor quality.

Once the fish have become acclimated and are on a regular schedule they will begin to act differently around spawning time.  You will notice that the female suddenly gets thicker in the middle of her body.  This could be an indication of a pregnant clownfish.  You also might notice that the fish are constantly cleaning off a rock with their mouths and fins.  This is to get the site clean for the eggs.  When the day to lay eggs does come, you will notice a small tube sticking out of both the male and the female.  On perculas it is in the center of their middle white stripe.  This tube is where the eggs and sperm will come out of.  First the female will swim back and forth on the clean part of the rock depositing eggs.  When the male gets his turn he also will swim over the eggs to deposit sperm to fertilize the eggs.  For close to an hour the fish will swim back and forth over the rock depositing eggs and sperm and constantly airating them with their mouths.  If you missed the laying of the eggs, they will be stuck to the rock the fish have prepared and appear as an orangish color.  The male cares for the eggs and will constantly swim back to the eggs and wave his fins on them to keep them aerated.  You might also see him blowing on them or picking off the eggs that are dead.  The clownfish will be very territorial about the eggs.  Any fish that comes too close, regardless of size will be chased away or nipped at.  This also goes for hands in the tank.

Happy, healthy, and comfortable fish will be more likely to lay eggs.  Be patient with your clownfish and one day when you are least expecting it, your fish will begin to spawn.  It can be a rewarding experience if the proper steps are followed.

    i have a marine aquarium and i am only 12. i hope to buy a mating pair of clowns soon and hope that i will have the capability to bring them up. i would like to thank the creator/s of this website for giving me this valuable information. so thanks guys, keep it up!

  2. Scott — October 13, 2008 @ 10:09 pm

    Best of luck to you. Let me know in the forum if you need any more help.


  3. shaina — November 3, 2008 @ 10:54 am

    what do you do with they eggs after? someone said you should take them out and put them in another tank so the corals won’t eat them?

  4. Laura — January 30, 2009 @ 12:07 pm

    I am so excited to find you site! I have a mated pair of gold strip maroon clowns that I have had for about 1 1/2 years. I noticed some eggs in my tank the other night and your site confirmed that they belong to the clowns! I had no idea that they would start breeding. I am not prepaired to try and hatch them in an controlled environment now. But I have gotten excellent information for the future. One question I have is if I were to take all the other fish out of my tank will the eggs survive?

  5. Scott — February 5, 2009 @ 1:53 am

    The eggs might survive but it depends on the size of your tank. If the tank is too big the fry won’t be able to find the food unless you have a ton of rotifers. I really think you have to remove the clownfish babies and put them in a smaller tank where they can find food.

  6. Carrie — March 18, 2009 @ 5:51 pm

    Thank you for the information about breeding clownfish. We have had a pair for almost 2 years and in the last month have laid 2 sets of eggs. But both times the eggs look small and are white-ish or clear. I have never seen them looking orange at all. Is there something we should be feeding them that will help with healthier eggs? We currently feed them frozen prepared cubes (called Formula 2). Thanks for any help.

  7. Scott — April 1, 2009 @ 10:21 pm

    The eggs are only orangish the first day or two then they turn a greyish color. The first couple time that the clownfish lay eggs, they sometimes are not a healthy batch. Keep feeding them high quality food and they should improve. The fish also improve with practice. Please see the forum.

  8. DR.PAULRAJ MURUGESAN — April 3, 2009 @ 10:06 am

    can i breed clown fish in artificial sea water /

  9. lance — April 13, 2009 @ 4:03 pm

    all of the information that you put on here is great and i may have missed the answer to my question. but anyway here goes. i have a 38 gallon tank all i have in the tank is live rock and 2 small clowns that i am raising for breeder fish. if that is the only two fish in my tank, is there ever a time that i need to remove the eggs or babies from the tank and put them in a separate tank. thank you for your help.


  10. Scott — April 15, 2009 @ 6:59 pm

    I would put the clownfish fry into a separate tank. It allows the clownfish babies more of a chance of running into food (live rotifers). If they have to search an entire 38 gallons for food, they are less likely to find any since the tank is so big (unless you really really use a ton of rotifers). There is also a risk of the parent clownfish eating the babies. Keep us posted in the foum.

  11. BSmoove — August 2, 2009 @ 9:50 am

    this was great. I’ve noticed the larger clownfish being aggressive to the smaller one and figured what was happening but didnt know what was going on wih he smaller one as he was acting as though he was having a seizure. I’m so glad I read this, yo’vereally helped me out and answered the question that has been running through my head for a couple of weeks now. Thanks!

  12. Sim from australia — August 29, 2009 @ 1:51 pm

    hi my names sim and im only 13 im going to buy a wall tank and marine fish but i want to use the money from breeding clown fish to buy better marine fish so i just wanted to know how long does it take for the proses of sexing mating and laying the eggs take because i would like to see what i should do,,,
    Also when i but the clown do i have to use live foods I.E. shrimps and small foods like that in sted of flake food

    thank for you’re time


  13. jerome — September 10, 2009 @ 5:16 pm

    thanks for the information. really helpfull! these arent my fish set of clownfish but these r the first pair to be in breeding mode for me. im quite excited! but pretty scared at the same time. thanks very much!

  14. Bluangel — September 30, 2009 @ 8:15 pm

    I am interested in breeding clownfish, I would like to know if I can put different species in the tank together, or will this cause chaos?


  15. Bazza — October 10, 2009 @ 7:36 am

    Thanx i bought two clowns not a mating pair about two days ago and the big one was biting the small one and getting the seizure thing.Most people strugle to get them to go in the anemone but myne was in straight away. I wil post again if there is any progress or if i need help. Great forum thanks

    hi do you think they will lay eggs on dead coral rock

  17. Amanda — October 24, 2009 @ 7:40 pm

    I got my clownfish about a month ago and been seeing the clownfish are folowing each other. One clown has been getting bigger than the other. I am trying to breed them. Are these a good sign that they will be good breeding fish?

  18. Amanda — October 24, 2009 @ 7:41 pm

    About how old should the clownfish be when they start breeding? Thanks

  19. Christina — November 19, 2009 @ 9:59 pm

    I have two clowns that r soon to lay eggs, do I remove the eggs when they turn the grayish color or do I wait until they hatch? If I wait til they hatch how will I get the little shits out of the 220 gallon tank they currently reside in?? Thanks for any help u can give me!!

  20. joe — December 1, 2009 @ 2:49 pm

    I would say up to a year for them to become sexually mature.#But usually less.

    okay i have a 45 gal salt water aquarium that i had just recently purchased about 4 months ago and i also have 1 black clown and also 3 orange clown fish. okay so here goes my Q now can the black and my orange clown fish breed and also is there to many fish in my tank i have a total of 6 fish including my clown fish.

  23. simon janes — January 23, 2010 @ 5:14 pm

    hi great website.
    i have had 2 clown fish in my tank for a year now and are both together in and out of an anenome. there are others in the tank including an eel and some crabs. naso tang yellow tang. 2 damsels. Obviosly any eggs that are laid will not last long. whats the chances of them laying eggs anyway. every thing in my tank get along fine. ive never really thought of breeding clowns but would love to give it a go. The 2 clowns were the first fish in the tank and they seem to be really happy and healthy. n e ideas.
    thanks for all the info given. a very good site

  24. Scott — January 25, 2010 @ 12:01 am

    You never know they might start breeding. Keep us posted in the forums.

  25. Scott — January 25, 2010 @ 12:07 am

    Yes 6 fish of almost any size are too many for a 45 gallon aquarium. You are also creating a stressful situation for your clownfish, if you want them to breed. Yes black and orange clownfish can breed together.

  26. Scott — January 25, 2010 @ 12:10 am

    Remove the rock when the eggs turn grey and you can see the silver eyes of the fry. Only remove the rock right before the lights are about to go out and it is time for them to hatch. Allow the parents to take care of the eggs as long as possible.

  27. Scott — January 25, 2010 @ 12:12 am

    Yes clownfish will lay eggs on just about anything including dead coral heads and rocks.

  28. Scott — January 25, 2010 @ 12:15 am

    Best of luck to you. Thanks for stopping by. A varied diet is good for the clownfish including flake, pellet, and frozen food.

  29. Simon — January 27, 2010 @ 4:21 am

    how big should my fry tank be and how long can they stay there For on an airstone only. Will I need to fully cycle tank or can I use water from my excisting tank. Cheers

  30. Scott — January 27, 2010 @ 10:06 pm

    Use water from your existing tank. A 10 gallon tank works fine and isn’t too big that the fry can’t find the rotifers. You will have to closely monitor the water quality and do daily water changes.

  31. nick and krissy — January 30, 2010 @ 9:56 am

    Hi, I have two false black ocellaris clowns, I bought then as a pair. Watching them at the fish store week after week both of the fish have been following eachother, the guy at the place of purchase thinks they will breed. We currently have a 60 gallon setup with alot of live rock. I wanted to know if they will or have determined a sex yet? One of the fish is a bit bigger but it is not that noticable, does this mean they are to juvenile still? When they do decide to breed, when it comes time to pull the rock out of the tank you would say it is best to make sure the eggs are not exposed to the air ? I am really interested in breeding my clowns if this is the route they will take. How much is the Rotifer culture and the food that this culture eats ?
    Thank you for all of your advice I have learnt alot !

  32. colyn — January 30, 2010 @ 2:14 pm

    i want to start breeding clown fish for my store. in the article you said to put them in a smaller tank. how do i get them from 1 tank to the other?

  33. Devon — January 30, 2010 @ 2:49 pm

    can pumps push the baby clowns into the filter and die??
    i had shrimp eggs hatch before and it looked like they were getting pushed around everywhere from the pumps

  34. Scott — February 3, 2010 @ 12:42 am

    As noted, you need to create a siphon with air line hose. Siphon the fry out of the tank and into a smaller tank.

  35. mohammed.nawaf — February 10, 2010 @ 3:36 am

    Do Adult Clown fish eat baby clown fish ? plase tell me ok ?

  36. Ryan — February 19, 2010 @ 1:16 am

    You dont have to siphone them out you put a small flash light point it on the top of the water when the fish are hatching they go to the light hold a bowl in the water where the light is shining then siphone the rest of them out,

  37. Kalen Crawford — February 19, 2010 @ 9:51 am

    I’m starting a black & white true percula breeding 10 gallon with 8lbs. live rock and 6 2inch square tiles 15lbs live sand and crushed coral. aqua tech 5-15 filtration till eggs are laid then switching to octogon shaped undergravel modified to sponge filter. This is the identical setup that i’ll be using on two other breeding tanks for a pink skunk pair and a fire clown pair. i always have several tanks on stand by in case of ammonia spike or any other type of contamination. This is my first time breeding i feel totally prepared having read everything and the internet is wonderful, and remember you can never have too much knowledge or back-up equipment just in case. Remember you could ultimately be growing MONEY so treat them that way

  38. Scott — February 21, 2010 @ 10:59 pm

    Yes adult clownfish have been known to eat the young fry. This is why you need to move the fry to another aquarium.

  39. Randy — March 3, 2010 @ 11:33 am

    Yes, This makes me feel fantastic, because i just recently got 2 clownfish and they were fighting quite a bit and they are the same size and I was researching and learned that you should get one bigger then the other. Also one of mine did exactly what you said did a little siezure on its side and i thought, OH no its sick….. but no maybe its not!! great news. But I do have a yellow tang in the tang also and its in a 29 gallon fish tank, I am planning on getting an blue tip anenome in about 2 weeks but in about 3 months all three fish will be moved into a 150 gallon fish tank that may have a brown powder tang in it. WIll that be a problem, will the yellow tang be a problem for them?

  40. Scott — March 23, 2010 @ 10:46 pm

    That should not be a problem, but the powder brown and the yellow tang could possibly fight. They probably won’t bother your clownfish though. You should get the fish into the bigger aquarium as soon as possible though. A 29 gall is too small for all of those fish especially the tang that likes to swim around a bunch.

  41. Michelle — March 24, 2010 @ 5:44 am

    Hi There, i wonder if you can help. I brought 2 young clown fish together & have had them for 6 months. They have worked out their sexes. I recently brought an anemone & they have been very happily making a little home for them selves. Everything seemed to be going fine & it was looking like they were going to lay eggs soon as they were being very territorial. But very sadly last night when we came home we found the little male dead in the tank, he seemed fine in the morning & i have done a water test & all is ok. All the other fish are happy in the tank. Have you seen this before? I wondered if it was something to do with the breeding process, maybe his little heart gave out… The female now seems very distressed & is guarding the anemone. I do not think we have eggs as i cannot see any. Are they usually easy to see? What would you advise will she breed with another male? Should we get another clown just for company anyway or will they fight? It’s such a shame to lose one at this stage.

  42. Randy — March 30, 2010 @ 8:31 am

    Hi, my one clownfish just constantly attacks the other and the other just hangs around the top of the tank and is scared, will this constant attacking finally end, and they will just get along, because the other one has already said it will be the male many times when it rolls on its side and twitches, or will the one being attacked die?

  43. oceanunderwater — May 22, 2010 @ 9:21 pm

    I currently have 2 clowns hosting in an anemone in my 65 gallon tank. I got them both about the same size but now one is much larger (presumably the female). I don’t really want them to breed (if they do great) but I would like to add some black and white clowns to the tank. I’m wondering if it’s a better idea to add another anemone and 2 b&w clowns (hoping they’re host in the new anemone & leave my other pair alone) or if I should get 2 or 3 b&w clowns that are much smaller than my current clowns (& hope they’ll co-habitate). Not really a breeding question but you seem to have a lot of knowledge of clowns & their behavior. I don’t want to upset my current pair.

  44. Eddie — May 24, 2010 @ 6:03 pm

    Hi there,
    I have 2 true percs in my tank and I have a very aggressive clown that relentlessly attacks the other. The submissive clown twitches to submit and the dominant one leaves and as the other tries to relax the aggressive one continues the assault. I don’t know what to do. Should I get a smaller clown? They are nearly the same size. I would say about 1 inch 3/4 or so. The dominant one has more black markings than the other. Could this aggression also be due to the fact that this submissive clown fish replaced origional mate? Any insight would be appreciated.

  45. matt — June 6, 2010 @ 7:01 pm

    my mated pair just laid eggs im concerned cause i also have 2 tangs in tank a butterfly copper band wich likes to eat everything off the rocks are my eggs going to be safe until they hatch then i will be able to transfer them
    any usefull imformation would be greatly appreciated
    thank you matt

  46. Evan — July 4, 2010 @ 11:15 pm

    I just had a pair of “nemo” clowns successfully breed on a rock next to their anemone. Before I passed out in the middle of the Coke 400 I had noticed that the young had left the rock and were swimming in quiet areas in the tank.

    This morning before heading off to work I had to pluck 2 of my larger (and now dead) fish out of the tank. Another small one followed when I showed up at home after a long shift. Fortunately they were really CHEAP.

    All of the babies are gone and these 3 regulars mysteriously died within 24 hours of their leaving the nest.

    Am I missing something here? Can newborn clowns kill fish if they’re eaten up? Can stressed (or depressed) parent clowns kill much larger species at will because they’re being protective?

    The water’s fine and the tank was 20 percent changed last week. I’ve turned the lights out to soothe them out some and all of the rest seem to start losing the will to live unless the skimmer is running full time.

    Any takers? Cheers.

  47. Dave — July 8, 2010 @ 2:58 pm

    Hi i have a 12 gallon tank with about 20 pounds of live rock with 2 clown fish that i got from babys 1 fire tail goby a star fish about 8 hermit crabs and a few snails that i had for about 7 months now will the clown fish breed in this and if they did would the hermit crabs, snails or star fish bother the eggs i was reading down this form and seen the part where if one of the clown fish start twitching they are chosing between male and femaile and this has been happening so i just want to be prepaired in what to do if i seen eggs in there one day?

    im 10 my dad has some experience with fish but not much,ive noticed my male clown fish is cleaning a certain rock but its plastic could he be spawning?Also hes not coming out to eat should i be worried? hes been dancing infront of my female and hiding under that rock what are they doing?

  51. Melinda — October 27, 2010 @ 11:00 pm

    hey i have 2 clown fish i have had for a few weeks now im not sure how long the lfs had them but i bought them as a pair they seem healthy and all but lately they have been acting strange like staying at the bottom of the tank all but for feeding time one will go eat then when hes done or she the other will go back to the spot while the other one eats i dont see any eggs or anything and they look healthy and happy would you have any idea whats with the weird behavior?

  52. Alicia — November 8, 2010 @ 1:28 pm

    Hi! Love this site! Tanks for all of the awesome information. In my 55 gallon tank, we have a pseudochromis, 4 little hermit crabs, 2 turbo snails, 3 blue-green chromis’s, 1 brittle star, 3 molly’s (can’t wait for them to be gone, they are heading to a new home soon) and last but not least – 2 false clowns. We have another tank, it’s 25 gallons it’s currently empty, has only live rock in it (hopefully seahorses can go in that one.) These tanks are joined by a sump system via homemade overflow systems and a homemade protein skimmer as well. *whew* that being said – we have been hoping that our clowns would pair and breed and they stay relativity close and after being away from our house for over 24 hours, we came home to our larger clown being fatter. (this larger clown was smaller but in the past month has gotten bigger and bigger and is almost growing bigger than the other clown by day). With this clown having a “pregnant belly” it seems s though they may be breeding. But my problem is that they are not cleaning any surface anywhere. They bigger clown is staying in her clay pot and doesn’t leave except to grab food from just outside. But still, no cleaning. Will it begin at a later stage? Is them cleaning crucial? How big will her belly get if she really is pregnant with eggs?

    Hopefully you have some words of wisdom for me.


    (ooo, we also have green hammer coral)

  53. Max — December 29, 2010 @ 12:35 am

    Im Max and Im 12 years old. My tank is 60 gallons. I have a pair of False Percula Clownfish (Ocellarus Clownfish), a Lawnmower blenny, 6 or 7 snails, 1 blue legged crab, 6 or 7 hermit crabs, 1 brittle star, about 30 recordias, 2 bubble tip anemones, 1 xenia and hammer coral, and 75 lbs of live rock. When we bought the tank, we did not know how old the one and only clownfish was (clownfish was supposedly female) we then bought a juvinille clown, a lawnmower blenny, and other crustacians listed above. I am hoping to get the clown pair to spawn, I even bought a 4 in clay pot for them to lay eggs on. I know that because we got the juvinille clown only 3 weeks ago, my clownfish may not be laying eggs any time soon. We feed them fish pellots, and frozen fish food. I was just curious when they might start breeding and laying eggs. Also, my clownfish seem happy together but also the female bites the male and the male starts having a “seizure”. Thanks for taking the time to read my comment.

    Hi im seth and i’ve had my two fales perculas for alomast a year now and they have mated off and the sex change is obvious and i have about 20 pounds of live rock in a 14 gallon biocube tank. the rock is very pores and has lots of hideing places for them also i have one bubble tip anemone. five fish in total. two enenier gobies and one watchmen gobie then the clowns.the gobies stay under ground all day and the clowns love the anemone. i have anbout twelve crabs along with one anemone crab and one brownish red crad that i cant seem to identafy. it only seems to eat the crap off of the rocks. no snails. i also keep the tank at 70-75 degres. i have grass growing off of the live rock and the clowns seem to like that as much as the anemone. i feed them a mix of flack foor and brine shrimp twice a day at 10:00 am and 5:00 pm. the anemone is healthy and so are the clowns. i run the tank on a live rock filter ensted of the plastic balls it comes with and i also have a skimer thats cleans well. my tank has never had a bad ph or anything like that. so clean water. honoestly the only thing i can find wrong is the tank size and it makes me mad that they arent breeding yet. but i understand i have to wait and keep a complex attituide about the whole thing. so thanks for what ever enformation you can provied.

    i would like to get a pair of Snowflake clownfish for breeding. How long did it take for your clowns to start breeding? Ive a 120 gallon reef tank and I’ve been thinking about setting up a 29 gallon in the bedroom for frags and the breeding clowns.

    Hey, this is a great website, I’m only 12, and i just set up my reef aquarium about a month ago, it is 30 gallons with about 50 pounds of live rock. The aquarium has been up for almost 2 months now.I was thinking it was going to turn out to be a coral only tank but now i have a scooter blenny, and a occelaris clown, which i bought today and it seems to be doing fine. I want to breed a pair, but I don’t know ,if I get another, that they will be young enough to change sex. If there is a way to tell, should i get another soon?

    my male clownfish died leaving the pregnant one alone. What should I do . I bought 2 brighter clownfish but the pregnant clownfish is starting to fight with them such as locking jawz. Plzz anyone reply. Need help Scott.

    My common clowns have been together 4 days. But one of them seems to be staying in one place and chasing off the other 3 fish I have if they come near. Is it possible they could have laid eggs within the 4 days of being in the same tank?

    we have got 2 black and white clownfish, with 2 little silver fish in tank. 2 nemo’s have been acting funny chasing each other round etc. are they starting to spawn? we only have a fake rock in the tank which they love. have made a hole at the bank moved the bottom rocks around on tank. should we get rid of the 2 little fish? i havent seen any eggs yet. should we put eggs in seperate tank when they turn grey?? have no idea here.

    Hi Scot , I would like to know is it ok to mate a black and white clown with orange and white clown fish. What color would they come out? Thank you in advance for your assistance. God bless you.

    Hello, I have a Q. I own 2 niger trigger fish, 1 mono fish, A clown fish, and a Snowflake eel. If I wanted to start a breeding process with the clown, would it be possible? I own a 55 gallon tank with plenty of hiding spots, the trigger fish are on seperate ends of the tank and the eel has his cave. They are all squared away with their spots. Do you think it is possible for 2 clownfish to breed with one another with what I listed in the tank? I’m hoping for a good reply! Thanks :)

    how long does it take to mate clownfish

  70. D — April 2, 2012 @ 10:42 am

    I have a 9 gal. tank and 2 clown fish and a small scooter blenny. They all seem very happy and my clowns have already chosen the female, the only twist is that on is a black clown and one is a regular clown. I was wondering if these guys could spawn. They never fought they seam to like each other except at feeding time when the orange clown (female)
    nips at him, but then he submits. You said thats ok, but I was wondering if that means they will spawn or not.
    The female is looking kinda fat, if you look at her striat on you can see her belly pop out. Could that means she is pregnant or just over fed and fat? the other one isn’t fat at all you can’t evern see his belly…one last thing is if they are going to have babies, I have a samll hermet crab (think he is a blue knuckle) and a porcelain crab, will these eat or destory the eggs?
    Thanks for your time

  71. Scott — April 2, 2012 @ 11:04 am

    Its hard to say if the clownfish is pregnant or not. You will just have to wait and see. They should lay eggs withing a week or so. Is very possible your crabs will eat the eggs, especially the porcelain crab. I would remove these should your fish actually lay eggs.

    Ok thanks so much for the insight. Your forms really helped!

    When is the breeding season for the clowns?

  74. Scott — April 9, 2012 @ 10:42 pm

    Clownfish breed all the time. There isn’t really a particular season in captivity. They will lay eggs take care of them until they hatch, wait a bit, and then lay eggs again. Every 12-18 days.

    Hey, Great info for a beginner at this. I have had a mated pair of Black and White Osc. Misbar clowns for bout 5 months. Never showed any breeding habits with previous LFS owner (3 years). In 29gal Bow super aggressive but never laid eggs even with multiple RBTAs and super water clarity. Moved them to 90gal with worse water clarity and inadequate flow (work in progress) but now they have laid eggs! Should I leave the fry in there once hatched or let them grow past a certain age before attempting to remove? Also was about to add new canister filter and powerheads… Leaving the tank as is with water changes atm. Thanks for all the other info.

    what age do clown fish start breeding

  78. Missy — July 28, 2013 @ 5:24 pm

    Hi, I am. Not the one with the tanks my brother in law lives upstairs from me and he has 4 tanks all kept immaculate and in excellent condition. He also has a water system hooked up where he filters and prepares his own water. Now they are all saltwater tanks and the largest tank has 2 clown fish which have had like 4 sets of eggs however we didn’t know how to get the babies out and the fish have chosen this one particular piece of live rock they lay them in same place every time now I actually videotaped the entire prep. And laying and fertilizing of the eggs. They will hatch in 4 to five days and I was wondering since they are on one side of tank if its possible to separate rest of fish from the area using piece of plexi glass as divider then once seeing them start to hatch syphon them out into a smaller tank prepared with same water and the proper food they are suppose to eat. I would really like to help him keep the babies I mean these two are definitely a great breeding pair they have done this 3 times in past 2 months and one time a year ago but the anemone had moved to other side of tank so it messed up where they bred not to mention the fish ate eggs off rock cuz they weren’t hidden due to the anemone. Well if you could offer any helpful info I would greatly appreciate it. You seem to know what you are talking about. Thank, Missy

    […] Here is a good little read, but I have a friend who has successfully hatched a number of clowns and currently has a dozen that are about 1/2". Seems like somewhat of a pain but I would start a rotifer culture asap or plan to buy live ones. And you will need a separate tank that you move the eggs to just before hatching.
