Omnivore that in aquariums eats all the usual food.
There has been some speculation about the natural environment of this “species” but many believe that it is found (or recovered) in fairly cloudy water which is the reason for their clear colours, however there are also other reports that it also live in reasonably clear water.
The Endler's guppy is an easily bred livebearer and gives upwards of 20 fry per spawn. This means that there are quickly too many fish (if the aquarium is small) so you have to constantly pick out the fry unless the aquarium is large.
The species is reasonably peaceful and can be kept together with other species. It is also not as hard on fry as the “regular” guppy. Normally, it is also slightly more hardy than the usual guppy. It is also slightly smaller but this is because the “common” guppy found in the stores are cultivated to be large and colourful and are therefore considerably larger than their original nature-forms.
A suitable aquarium should contain some plants, preferably free floating plants. Males are significantly more colourful than the larger females (males become 2-2.5 cm max.).

There is a lot of speculation about this species. Some believe that it is simply a “common” guppy, others mean that it is a variant of the “common” guppyn, others that it should in fact be named Poecilia wingei (newly discovered species (also called Campoma guppy) whose species description also is disputed), others argue that the Endlers is a crossing between just P. wingei and P. reticulata . Unfortunately, no one seems to be able to recover the Endlers in Cumaná, Venezuela where it is originally supposed to have been caught, so likely we will have to live with these question marks for a long time to come. In stores today there are several breeding forms of the Endlers that may have different colours and/or caudal fins. Many of the Endlers found today in trade are probably crossings between different species. The photos used in the species description (photo 1-3) show Endlers originating from a population purchased in the United States just over 15 years ago (has since been held by the same person) and then said to come from a wild-caught population.
