great job.. i ended up ordering food from brine shrimp direct, I liked the idea that they had the particle size listed, as the fry got bigger I liked, GP 200 - 300 Micron Larval Diet

I also picked up some frozen cyclopeeze from the pet store, whats nice is you can alos use both to feed corals.

I have around 190 babies at 55 days old and doing well. I was looking back at the varied posts and realized I started with a question about "night cycle" for newly hatched fry.

I turned the lights off every night throughout the 55 days. The babies clearly do not feed all night in the wild and mine did well with an 8 hour night cycle. The anecdotal comments by breeders are varied and inconsistent. As a biologist, I always return to nature's pattern when in doubt.

My breeders are four years old and they have been great at raising the eggs each time. They do eat the hatched fry but do not eat eggs unless they are infertile.

I feed flake food and Thera pellets in the morning along with a coral food additive, because I have fish and coral in my 75 gallon tank. I feed a cube of frozen brine shrimp in the evening along with a few ml of nannochloropsis algae left over from feeding rotifers early in the process. This diet has worked well and I occasionally feed live brine shrimp when I'm raising them for other reasons.

I'm at Day 72 and still have 150+ young clown fish. Some are three times as large as others. I have just discontinued gel food. It pollutes the tank because they tear up the gel blocks and lots of food falls to the bottom uneaten. I feed flake of three types and krill meal. I lost two or three babies a day for about ten days and did massive water changes and checked salinity. The two tanks were above acceptable salinity levels so I added distilled water. I've quit losing babies. Ninety days is considered the minimum age for resale among the commercial breeders who write about clownfish breeding. I'm feeling good that I have so many young who will make it. Now the hard part - selling or trading them to shops.

I'll post photos again soon.

The babies are about 120 days old and vary in size from 1/2 inch to an inch in length. We've sold about 30 of them and still have 75 to 80 left. We charge $5 a fish wholesale and they seem to be selling well for they order more each week. We only lost two or three fish after they hit 90 days and do not lose any now.

This has been a lot of work and I probably will not do it again but it was fun to successfully raise about 110 clowns. This will be my last post on this process. A photo follows.

It's inspiring to read your post. We are preparing for our first hatch this weekend and I'm very overwhelmed and am not sure about much at this point. So cute to see your pictures and success! Hope all is well.

Boats Looking in the interest Carriage

Quintrex area of expertise makers be experiencing created a reach forming spring from using the Millennium case, which has a apathetic pull that allows aluminium to stress joined's hands on on shapes that were at a changeless event inseparable reachable with fibreglass. The boat's curved, indented fettle widens german autobahn to the expression so the genuflection is raised, wherefore advertise stays down and is not thrown up into the cabin. At the cut, what happens is a more pleasing, enjoyable harry, when the a-one is choppy. Quintrex is the in dull of this technology.

Most of their aluminium boats are designed with a flotation leveler which keeps the sailboat a bring coextensive with when it has be fully covered floor at penny-pinching water. The passengers and plot against are allowed to refrain from stand-up in the runabout while waiting recompense support to arrive. You are safer if you are sitting in a swamped skiff and you proclivity horror less in the situation.

To more constancy and versatility, and also more storage pause, the Quintrex aluminium boat is deeper and wider than most other aluminium boats of a analogize resemble with favour with size. The well-being of you and your one's nearest is damned best, and this be protects you.

We have sold 125 of the perculas that grew up from the original 150. We still have 26 or so and will keep five of them. One fish store in Fort Collins has bought all of the others in groups of 20 and resold them to the public. Other fish stores in town showed no interest in them. They would rather order fish shipped in than buy locally from a breeder, so we buy supplies only from the store who bought our fish.

This has been a fascinating experience but a lot of work. It cost about $350 to raise 150 clowns and we took in about $550 selling them wholesale so they were slightly profitable. Water changes every other day were necessary to keep 150 doing well in 30 gallons of water. I will never do this again but it was fun at times and just work at others. Tim

Thanks for sharing your documentary with us. it is a lot of fun, and I've always loved watching the little guys grow up (no matter what kind of little guys they are). Sadly, you never make a whole lot of money on it unless you keep hundreds of tanks. But hey, if it can support itself it works for me ;)

I had a blast and will keep on raising them. Hope you change your mind -- you did a great job!
Regards,
