I've had my blue hippo tang for about 2 weeks now and the past few days I have noticed that his tail and fins are all tore up. He also has a white spot (I don't think it's ICH) on his side. He also looks kinda bumpy and his face looks a little bit up. I have been watching my tank and noticed that my Royal Grama (who is pretty big) chases the Hippo around the tank with his mouth open. Do you think the Grama could be causing the tail/fin problem? And what about the "bite" and bumpy marks on the hippo? The only other fish I can think that it would be is my Long Nose Hawkfish. The hippo loves to swim near the hawk but during the day the Hawk doesn't seem to mind. Do you think he turns into a Dr. Jeckel/Mr. Hyde at night time and is attacking my hippo? I just did a water test and everything is running perfect.
