The Endler's Livebearer is a very popular fish amongst many aquarists although its availability is sometimes limited in shops, leading to a large specialist breeders market. Endlers are very closely related to the guppy, and their appearance is very similar to that of the wild guppy, with males being small (about 2cm) and sporting bright patches of colour on the body, whilst females are larger (4cm) and plain. The colour patterns of males vary depending on the source and brood history although patches of bright orange, black, blue-green, and yellow-green are common. Wild strains have a dark band down the centre of the body and less variation of colour, but it is rare to see wild strains for sale. Almost all Endler's for sale are likely to have a small proportion of interbreeding with regular guppies at some point in their genetic history.
Endler's have now been officially classified as an individual species, although they are so similar to guppies that interbreeding is possible, and viable offspring are produced. It is best to avoid keeping the two species together so that this does not happen.
Endler's are easy to care for and relatively hardy and adaptable although they do prefer warmer water (20-28C) than wild type guppies and are fairly short lived, with a life-span of up to two years. Hard water is preferred, and since they are small, avoid larger tank mates. A very colourful and interesting fish, ideal for a community of small fishes.
