Check out this pic...My Bi-Color 500 was trying to get my Eruptus Syn to clean something off his body....he kept on swimming up to him like an Angel would to a cleaner shrimp in a saltwater tank...and sure enough the catfish swam up to him and appeared to remove something...maybe a parasite? Maybe a scale? Who knows...I took this pic with my iphone and havent seen the behavior since....anyone else ever see this?
