their in a 60gal, it's ok for now, upgrading to a 140gal in jan. my FH and Pbass are in a different tank with the RTGG's. yeah, was concerened about the butti's aggression against the oscars. i've been watching him for 2 months at my LFS. he was in a 30 with a around 15 other pretty agro fish, GT's, Texas, and the semi agro oscars. i'm on good terms with the people there and we've been watching the butti for awhile. seems he's more territorial then simply agro. none of the other fish ever went to his side of the tank at the LFS. seems that he's taken up the same pattern in my tank. at first my 3 oscars mobbed him, but the butti put a stop to that very quickly. now he has established his territiory and none may enter (except the salvini and red-head)i have barbs in there as distractions to hopefully quell tentions. i'm hoping i have a mildly tempered butti, but i know of their track record. as of know everyone is getting along,i'm hoping it will last, he is a beautiful fish. thanks for all the comments and info
