I'm visiting a friend for the holidays, and her tank distresses me. She has two full grown angel fish and three gouramis. The angel fish have tiny black (1-2 mm in length) dots attatched to their top and bottom fins. The don't seem to affect the fish, and I'm told they've had them for the past year. What is this?

Black dots?

Hard to say without pics.

You sure it's not just their natural coloration?

are there any lumps on the angelfishes head? possible HTH(hole in the head) maybe a pairsite and yes it's hard to say what it could be with out photos. are the angel's eatting and breating normally? did she QT the angels before putting them in the tank?
it's just my opinion, but I say all discus and angel fish need to be QT, before being put in to a tank.
