I want to add more GBR's to my 46. They are the best fish. So much personality. I was thinking of adding 3 more. I have the space. I'd like to get another golden one for the one I already have. I believe it's a male so I want to TRY to get a female. If they pair up and breed that's fine but that's not my goal. And then I'd like to get 2 more regular colored gbr's. Should I try to get a pair or 2 of the same sex? (I'm not interested in breeding.) I just wonder if it would be overkill on that many gbr's since they can be kinda "pushy." I guess my question is if there is a limit on how many to a tank (within stocking reasons) since they are territorial?
