see i would say a GT would present a whole different prob. now you would have a gt terrorising the tank instead of the oscar, you would just be replacing a dictator for anouther one. i would say try to get a fish with simmilar attitude as the oscar. krussie maybe?BostonPatriot said:Blue Dempseys are beautiful but are a community tank fish to me. They also need perfect water like discus. I know I am always suggesting Green Terrors but they a beautiful fish that can hang with the big boys. I say get a Male GT!
