I don't think it's what I'm feeding them that matters. There appears to be something wrong with some of them. Although they all look fine, the larger ones don't have much of an appetite like the smaller Lemons. And those are the ones dying. I've lost 3 of them in the past 5 days. Water is good-0 amm, 0 nitrites, 5 nitrates, PH 7.6 temp 78F.
