my blackbelt and texas harrassed each other relentlesly in a 265 at 3 inches(had to rehome the texas)really depends on the personality of the fish(its 50/50)
i agree with budda, sometimes it doesnt matter about the room but the aggressiveness, if its just a pissed off fish, he's gonna f@%k up the first thing it sees. attitude
IMO it depends on the fish. I am about to trade my BB (I am heartbroken) but he has caused major issues in my tank and I think he killed 2 fish. GT, TX
I have heard some are ruthless and others are wimps.
I have had good Texas', and ones like everyone talks about. Fish are born with aggressive genetics, but not all act the same way. Best way to see is try it out, and keep an eye on everything.
love my black belt he harrasses alot of the fish but never does any damage,the only fish he ever fought was my texas,but my bb gets along fine with a synsplilum
