I have moved the culture to a 2 liter bottle with a air stone , so I will see how it works in multiplying the rotifers. I`m still new to all of this so I am hoping it works ! I still have two buckets of rotifers going ,so far knock on wood ,no Problems !
This morning some of the fry did not do to well

I Still have 17 in tank #1 and 14 in tank #2 ,but after a water change and later adding 3 quarts of 1.020 main tank water to each tank . Which took most of the day ,by the drip a sec method !The fry seem active and starting in hunting mode ! All have silver bellies and starting kink tails ,some just drift and eat (day 2 )
I am feeding tthe rotifers Dr.G`s Phytoplankton, It is all I could find for now . It might be part of the die off or maybe because of the late hatch . I dont have any eggs yet which Is good for now ,till I get the hang of all the work involved in raising fry. right now it`s trial and error. I probably need to do a water change .I get my sea water offshore when I`m in my boat !
Sorry to hear about your puffer fish ,I never had luck with them ,also not a good fish in a reef tank , they have been known to give off toxins into the water . I also have a small 7 inch snow flake eel in my reef tank .I didn`t feed it for a few days and made quick work out of my mated pair of coral banded shrimp . Hopefully when the ocean water heats up to 82degrees I`ll catch another pair of shrimp

I hope you find the book , I would call around first or maybe you can find it online . try Amazon .com, I paid about 24 dollars for my copy .
