the 2 fish in this tank ( shown here ) have been in this tank, I handed it over to the tetras, and pretty much gave up on dwarf Cichlids... but these 2 female apisto's, seem to be fine, on opposite ends of this 55 gallon... they have been here so long I forget the type, but they are the same species females... they don't seem to bother the tetras, being alone... I'd be afraid to add another male, and watch the in-fighting begin again... thoughts??? these pictures taken today at feeding, otherwise they have a tendency to hole up..
