I work at a lfs and today a customer wanted to buy the lone mai tai clown we had and put it with the mai tai he had in his tank already. He said he also had other kinds of clowns in the tank and they got along well. The question is that since our mai tai was alone, it would’ve been female, right? So would the one mai tai in his tank already be female because it’s the only mai tai and therefore he would have a fight to the death? Or would there only be one female in a group of multiple species?
