Will This Setup Work ?

I dont think it would work the GT gets to agressive with all the space it just might but if the GT gets a scale up its but your going to have some trouble on your hands. You could try it out but keep a close eye on it. GT get 12" and firemouths only get 6" big size diff convicts could get pretty mean to but maybe with enough hiding places it might just work out but still keep a close eye on it.

ya i agree that setup of fish is risky.....

yea i would say if u do do it would be to watch the sevreum too cause hes not very aggressive and could end up with every1 taking out their aggression on him too. but watch the GT vs Con action too. there wont be any breeding pairs in the tank either so no agression because of that tho.
