Only Males Left.
Overview
This Apisto is generally a peaceful species; however, they can become somewhat territorial when breeding. It would be better to keep these fish in pairs; however, if you have a much larger aquarium, it is possible to house one male with several females as they will form a harem. The females will establish individual territories, hence the importance of many visual barriers within the tank.
Good tankmates for your Apistogrammas could include Corydoras Catfish, small Tetras, Hatchetfish, Pencilfish, and Suckermouth Catfish. However, you should avoid keeping them with Larger, more aggressive species in too small an aquarium. Also, it would be best if you did not keep these fish with different Apistogramma species in the same aquarium.
