Mine spends a lot of time hovering around the top of the tank by herself. I find it a little unsusual because about every other cichlid I've ever had seems to prefer hanging out in territories on the bottom. If she does swim around, it's usually to chase the spotted pims or rose line barbs who are quick enough to avoid her. Recently I had to move a pink tailed chalceus that she almost bullied to death. In a nutshell, I suppose you could describe mine's behavior as that of a typical moderately aggressive cichlid. As for polleni's as a whole, from what I've heard and read they seem to run the gamut from fairly passive to extremely belligerent. I suppose that doesn't help you much, but they really are beautiful fish. Mine has a nice deep black to her and her bright spangling consists of all types of subtle shades (which doesn't show due to my low end camera and even lower end photography skills).
