Hi mike, I have two pairs of A. atahualpa right now and they are doing great. Despite what everyone tells me they are the least agressive of my apistos. I wonder though if this is because one of my males is obviously dominant in coloration and the heirarchy in the tank is not really threatened. anyhow I think that they are great fish. Good luck!
