I am looking for some insight on what happened to my 2 1/2 week old clowns last night. The clowns are oscellaris and were in a 10 gallon tank. There were about 35 - not a very sucessful hatch to begin with. Less than half of the nest hatched and many died in days 1-2. What was left seemed to be doing well however. They were eating BBS and I was weaning them to dead foods. Water quality was an issue, of course, and I added a sponge filter from the growout system last night. Then in the morning all 35 are dead, maybe one or two have some movement off the bottom.
I am insanely busy right now, so my husbandry is not up to par. This is probably batch number 18-20 from my pair and I thought I was getting the hang of this (not too bright). What I am looking for is some ideas on what I might have done wrong. Is there an optimum time to add a sponge filter to the tank and cautions I should have taken? Did I deplete the O2 in the water? PH swing? Maybe just the shock or sudden fright? This is something new to me, although I have lost my fair share of larvae for other reasons. I just don't want to do this to the next batch of 200 seven day old larvae that is sitting next to the now empty tank.
