The name livebearers is quite simple: fishes whose eggs are fertilized and hatched internally in the females body.

Black Molly (Poecilia sphenops): This is a jet-black fish with quite unusual dorsal fins (in males). With enough space the dorsal fin can become very big. This is normally a very active fish.
