Livebearers


Mostly native to Central America, these small, colourful fish are very popular because they are very hardy and inhabit all levels of the aquarium. Platys are probably the best example, a very good choice for a aquarium which has just started. 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.
