I‘ve had a royal gramma for about year in my 32g with 2 other fish. He started off fairly peaceful. Recently he has become an a$$hole. He leaves my clown alone but tries to lip lock with my watchmen goby. I recently added long tail wrasse and he nips and chases him around constantly. Feel like I need to get him out of the tank before he kills the wrasse. I had no idea RG could be so aggressive. Any thoughts or suggestions?
