Here is one shot of my recently spawned Oscura heterospila pair. I dare say, that imo, this species could be the perfect Heroine cichlid. I have kept them on three separate occasions in 11 years and never experience problems. Ideal keeping them in community biotope tanks with Thorichthys spp. and livebearers.
