My black ice clownfish have been breeding for about 3 months. I have attempted 5-6 time to raise them. The best I had was 92 past 8 weeks and they are all still going well. I have around 150 total now. The new fry seem to only die off during 12-48 hrs. After that, 95% or more of them make it.
My question is about how much airflow in the fry tank after hatching. I get 99% hatch rate and all the fry are swimming crazy the next morning 300+. The book and forums I have read talk about using a hard airline at 1 bubble per second to start and increase a little each day for oxygenating the water. I think my fry are suffocating due to too many fry and rotifers in a 5 gal tank. I just switched to a air-stone with medium to low flow which is 20x more oxygen and water flow than before and seems to be working much better.
I think it is a lack of water and air flow in the tank because the rotifers settle in the bottom 2-3" of the tank with so little flow and use up all the oxygen. The air-stone and more flow circulates the tank, mixes the rotifers, and the fry are swimming like crazy and eating instead of 1/2 of them lifeless on the bottom or sized with 20% of them swimming around the top.
Those breeding clownfish and getting 250+ thru meta per batch, what are you doing for aerating the water in the first 7 days.
Trying to see if this makes sense so and I'll try it on my next batch in 8 days. Once I changed on the current batch, they stopped dying immediately and I have 150+ currently.
