This has probably been asked a bunch of times already, but here goes. I have a GT in one 55gal and a Butti in the other 55. They are both outgrowing their tanks, so I bought a 150 gal. The GT is about 5-6" and the Butti is 7-8". What are the odds of the Butti not killing the GT in a 150 gal. They have never been together in the same tank. Right now the Butti is in a tank with some mbunas that are about 4" and he doesn't bother them.
