Hey guys. Just got a group of 5 leopard danios today to finish off stocking my tank. They are awesome little guys, so playful! I noticed one of them seems to be missing an eye though. It doesn't look red or anything, more like it was never born with one. Should I take him back to the shop to get replaced or will he still live a fairly full life? He seems to be grouping with the others fine and doesn't look sickly at all. Will keep an eye (ugh sorry) on him tonight. Never had a fish missing an eye before, so wanted to see if anyone had any experiences with them. Thanks!
