Me and my partner got 2 Molly fish about 2 months ago and ever since have had non stop problems. First we noticed they were developing white stuff on their eyes and kept going to the bottom so we bought a general fish medication from pets at home which seemed to do the trick, but now despite the fact they look better they both still keep staying on bottom of the tank and not moving my much...appetite is good. Ammonia levels at 0 and nitrate is still pretty high but unsure how to get levels down? Please help, we can't seem to get it right and fear we may lose them ?
