oh i know, i have a copper band butterfly, i see him picking on my crocea clam,, but my clam seems to be ok.... i dont know if the copper band is seeing something on the clam.. beautiful picture, does your angel fish seem to bother your other corals, i would love to have one, but i was told that they are aggresive, i have a mimic yellow tang,hippo tang, foxface, red sailfin tang, copper band, i have a surgeon fish i believe thats what it is called....or it may be a squirel fish.. would this angel fish pick on the other fish? thanks and have a great day...
