Billy who breeds them writes:
Aphyosemion species (sp.) Lobaye. They are related to Aphyosemion chrystii. Do well in 2.5 - 5 gal tank if want to breed. I keep them at room temp. 68-72 F with no problem. Soft, acidic water is preferred. Stock tank with plants or mops and wait for fry. They do OK with small tetras, rasboras or other small killies. Quite beautiful when mature. Mine are always out front.
