There is a thread in the data base of someone's experiment. The fish are pretty nipped up and tattered looking.
I think the key, like with any aggressive fish, is to keep the tank very densely populated to spred the aggression. Nevertheless, I am inclined to think that there will be lots of manuevering for dominance. And if there is a super aggressive boy he will spend all his time chasing and nipping.
Of course this is theorizing based on experience, past advice, and observation of aggressive fish.
