My LFS has a Copperband that I've been interested in acquiring. I generally don't buy a fish unless I see it eating, and every weekend for the last month I've asked to see it eat and every time they try feeding it, I don't see it take to food. However, it's been in the tank a month, so you 'd think it's been eating something. According to the guys at the shop, all they feed the tanks are PE Mysis and sometimes NLS. The tank in which the CBB is held has one piece of LR in it, maybe about eight inches in diameter and it looks super clean. There's nothing growing on it, though I the fish generally spends its time circling it and periodically poking at it. I'm interested in opinions on those experienced with CBBs - is this thing eating and I'm just not seeing it? Or can a CBB starve to death this slowly?
