ok thanksRWaltman;4837329; said:some of the smaller ones could be...such as Gymnogeophagus meridionalis which don't grow beyond 3-4", Gymnogeophagus' are usually much smaller than the geophagus'. Often they only hit 5" at max...some grow bigger, but usually 6" is it. I would be comfortable putting a harem of a male and two females with no other inhabitants in a 29 no problem.
