anyone had any experience with these angelfish and "cleaning" other fish? i have a starfish that developed some fuzz type layer over his entire body, couldnt find anything on the internet on it when i first saw it because it worried me. found nothing, starfish continued normal behavior/eating and i got this angelfish and he was like cleaning off the starfish. i also saw him do the same thing to one of my GSP's. it wasnt a sign of aggression, he just kind of pulled off some sand that was clinging to my GSP and moved onto whatever else he was doing.
