Nuno, I assume that this is a tank that will be plant oriented & with a low fish population. In this case I would recommend keeping your A. agassizii with a trio of a colorful macmasteri-group species. When they breed it will be easy to separate the juveniles of the 2 species. Your other option is to add a second trio of A. agassizii & watch the intraspecies actions put on by the males & females. In this case one male might take command of most of the tank and females, but your tank is large enough that there will be enough room for 2 breeding colonies.
