I keep both species. Phrynomantis bifasciatus is East African (see MTG article, link on left hand of the page), while microps is West African. Both are toxic, so don't house them together. Coming from West Africa microps, should be kept a little bit more humid. I keep both species on a substrate of sphagnum moss with a false bottom under that. I feed both species fruit flies, bean weevils, and pin-head crickets. Its really cool to watch Microhylids feed, as they can shoot their tongues out in many more directions than most frogs.
