Hey guys, a couple days ago I got a really good price on two very small butterflyfish...yellow butterfly (Chaetodon andamanensis) and a Threadfin butterfly...I forgot to ask the girl at the shop to feed them before buying so now I'm here at home with them trying to coax them into eating because one looks a little too thin to be honest (that's my fault for not specifying the exact fish I wanted at the shop). I've never had butterflies before so before I go buying all types of special food, is there anything I should know about feeding them? They're the only two fish in a new FOWLR and I do notice them picking at rocks looking for food but they aren't the slightest interested in pellets and their mouths are so small I'm not sure I could cut fresh food into small enough pieces. Any tricks I should try?
