The Amazon molly (Poecilia formosa) is a brackish-water fish of the family Poeciliidae that grows up to 10 cm.
Description
The Amazon molly is a small livebearing fish of the family Poeciliidae from Central America and the southern United States. The species grows to about 10 cm and inhabits backwaters and quiet pools of streams, ditches and sloughs, usually over mud. What is special about it is that it consists entirely of females: it originated from a hybridisation and reproduces by gynogenesis, in which sperm from related molly species only activates the egg but contributes no genetic material, so the young are clones of the mother. As an omnivore it eats algae, detritus and small invertebrates. The species is harmless to humans.
