I kept three 18-20" reds by themselves, and they were OK. I introduced a catfish, same size with them, and they just ate that catfish. Thing is, they tore chunks of the catfish, like piranhas. They couldn't sneak behind the Peacock bass. But after seeing what happened to the catfish, I had to separate them from my community tank. They seem OK by themselves. Someone bought all of them, and decided he couldn't keep them because they are psychos. nearly broke is 180 when he came home wth a bag of large feeders. They acted like wild dogs, splashing the water inside the tank. They are definitely TRUE monsters. Experienced keepers required.
I would take it with me, if i were you.
