We newly bought two rbs (3") in a 85 g tank. In two days they ate five goldfish. But sadly one of them wounded from one side. ( i think the reason is the sharp side of the rock inside of the aquarium.) And we caught it. ( it was so hard to catch him.) And we used some medical to treat him. After two days from this operation he is ok, looks healty but he is not as agressive as we bought. He is very very shy. Always hiding himself from us.. He is not eating anything. Do u know what to do to gain his self-confidence back?
