I Started with about 25 baby nyerereI fry about 16 days ago. I have them in a 10 gallon tank with a sponge filter where ive been doing 10-20% water changes a day or every couple days. Keep the tank at 80 degree's. Ive been trying to feed them baby brine, crushed up flake powder but I never seen them eat it. Starting a few days ago I keep losing them one by one. With them schooling in the corner behind the sponge filter and only ever seeing not more then 1 or 2 swimming about the tank even when I'm not near it. I Lost 1 or 2 the first day then a few the next and now today waking up with around 5 dead losing around 10 in total so far. I can't seem to figure out why they are dying, they seem weak and not in control of themselves, darting around the tank very fast randomly which ive only seen a few times and also eventually just floating around the tank until they die. I never seen them eat so are they just starving themselves to death?
