Thanks for the compliments and yes so far it has shown itself to be very aggressive, even at it's young age. I don't expect to house it with convicts over the long term ----don't trust him----- to big ,fast and powerfull and my male cons are big enough targets. Cons are tougher then tough but they really can't stand up to something like this if he can nail them, nor can they dish back anything in comparison. I figure I got about 6 months or less, until it becomes very high risk to house my male cons with him. I do, on the other hand, think that I can house him with black belts ( amongst other fish), eventually in an 8 ft. tank ----- if it doesn't work i can always move the BB back with the cons, as i know these 2 can co-exist well enough.
