I totally hate replying to threads like this here because it isn't what people want to hear and a hundred people who never had one for more than a year will dissagre with me, but I owe it to the fishes, so here goes'IMHO
Copperbands should only be raised by butterfly experts. Although they are considered to be moderate to difficult, heres the thing, for every Copperband you buy, hundreds will die to replace him. Whenever the distributor I worked for got them in, 50% were DOA.
