Hi there fishie people Up until a little while ago, in my shallow knowledge, i know of 2 tangs that shoal naturally, in rather big numbers, that is the Yellow tang and the Convict surgeon. There may be more, which sounds perfectly reasonable, but this is my query, i thought these fellas were beeches, and yet i see plenty of them. So there are two options here, its true and our small tanks could not survive such a thing, or its photo-shopped and is utter twoddle. And besides the point does anyone know what the darker surgeon is? i couldnt quite figure it out, maybe a ring tail?
