Angel fish

Question
my angel fish is swimming around and nipping at all the other fish making them stay out of one side of the tank and wont let anyone else swim on that one side what is going on?

Answer
Angel fish, like a lot of fish are very territorial. Yours is just letting your other fish know that that is his part of the tank. I never recommend tank mates for angels. I only keep angel fish in one tank. If is gets too aggressive, i would remove it from the tank and either put it in a tank by itself or take it to the store and see if you can exchange it for another fish. Is it the only angel in the tank? How big is your tank?
