Im bumping this thread because Ive been seeing a growing number of threads about people buying these fish without researching them first.
These are big aggressively territorial fish with the power and will to exert their aggression in almost all situations. Some will never accept tank mates unless kept in very large tanks with equally large and pugnacious tank mates where a truce can be achieved and appropriate territories can be clamed. I have said we create the situations that cause problems, not the fish. Please research this or any fish for that matter before getting one. They are all cute when young like puppies but if you buy a Pit Bull and then complain you cant take it to the dog park whose fault is that?
I hate to see a fish live a miserable existence or be discarded because we failed to be responsible fish keepers or wanted the toughest fish on the block and now that we have it dont know what to do with it.
