I have a black angelfish that is about 5 inches long and I think it is bullying my other fish. I have a 55 gallon with a gar, black ghost knife, Bala Shark, Angelfish, Raphael Catfish, and a Leaf fish. They all seemed to be getting along but now the shark and leaf fish are getting marks and what looks like bites. I think he may be bullying them because he is always chasing them. Is that normal for angelfish or is there just not enough room?
