Mesoheros gephyrus have paired

Well, it looks as if something positive may be happening with my colony of eight Mesoheros gephyrus. After basically ignoring one another for the last three years, they have finally started to show some interest in one another. There is sexual dimorphism beginning to show and a female, after giving a large male M. atromaculatus a look, finally has settled down with a male of the same species.
