Yes they will. Cecil has some in a tank right now.
Both Bruce and I have had no problem with them in tanks. I also have some in cages at the present time until I can sex them. The only time I've had problems is keeping large specimens in cages that were never in cages before, which is understandable with any fish. I had beat up pec fins which may have meant they were fighting. It was also a low density cage so they probably became territorial.
