hi i have a problem at the moment with the fish in my tank. i recently added a firemouth cichlid and my two kribs haven't taken well to him at all. i want to seperate them but i need to lay my hands on a new tank. if i wanted to put the 2 kribs in a new tank what would be the minimum size? they are not a pair as they are 2 females? they sometimes fight each other, but both have been ganging up on the firemouth and he just takes it. need to seperate fast
