Adult pairs with big males, yeah probably a 6 foot tank. Maybe a little smaller like a 5 foot 110 would be possible with territory established on each end, and nothing in the middle, to keep them apart from one another. Could probably make something smaller work with a divider especially if the fish were younger.
