I did some research before I got them and I wasn't sure if I would be able to keep them alive. It seems it just depends on the fish themselves. They've all been in here for a month (fingers crossed). I've heard of people who just had them die on them after keeping them for a while. I keep them at around 81 degrees and feed them frozen food, but they like the flake a lot too.
Have you seen any with a more white coloration? I had one that initially was mostly white, but then gradually is turning more brown, and now, one that was brown has almost turned albino on me. They appear to be healthy, but it is puzzling. I hope it's not sick.
