There is a lot of confusion to what these fish really are and as of yet have not been formally classified in their 66 years of known existence. They do resemble wild guppies in terms of their size and general shape. The colours of the males are much more striking with slashes of orange, metallic iridescent green and black, all variable in size and intensity. Like most Poecilia species the males are more highly coloured then the females and about half the full adult size. Males grow to about one inch but are intensely coloured to make them stand out. Their dorsal fin may be slightly coloured and they often have one or two extensions of colour on the caudal fin. Females are much larger then the males and have no coloration.
It is unlikely that they are a geographical variant of the original wild guppy. F1 hybrids between the fish can be formed occasionally but they form an infertile hybrid, not the same species at all. They also seem to be more streamlined and have more angular fins. The common name ‘Endlers Guppies’ comes from Professor John A. Endler who put the fish forward for classification in 1975, and their current Latin name stands at Poecilia sp. ‘Endlers’.
