I am growing one out now. I have had him for a few months. He seemed to only have a problem with my severums. Also developed HITH even though the other fish show no signs.
I had a few in the 15,000 for a few years. They were peaceful in it because they were among the smaller fish in it.
I have one male (wild caught) about 6-7" right now in a 180 grow up tank with a peacock bass about the same size and a small stingray. He chases the peacock bass at times. Eats mainly flakes and pellets.
