I have a school of 6 zebra danio's. Well, they dont school so much as zoom around the tank in every direction. Too the point....I have 2 Dojo Loaches that seem to enjoy lounging ontop of my a piece of driftwood in the center of my tank(55g). I had noticed of late that both of their dorsal fins were looking very rough, but only the dorsal. I had not noticed any niping till tonight, when after feeding, a zebra swooped down and pecked the fin of my dojo. The dojo didnt seem to notice. Is this normal behavior for zebra's? Any one have a sugestion?
