Endler Guppy: The Little Wonder


The Endler Guppy (Poecilia Wingei) is a family of the Poecilia Reticulata (Guppy), in fact if they are raised in the same aquarium, they could hybridize and also produce specimens that in turn would be fertile.This fish was discovered twice, first in 1937 by Franklyn F.Bond, although we owe its name to the discovery of John Endler in 1975.It is thought that there may still be some place where they can live in the wild, but it is difficult since their original habitats are highly polluted. The Endler Guppy specimens that we buy in stores come entirely from specialized breeders.

In the aquarium, the males are preferred by aquarists, due to their bright and metallic colors, which may be due to their original habitat, green waters rich in algae, hot and hard.This is one of the most obvious sexual dimorphisms, while males have colors ranging from red, orange, to turquoise blue tones. What is characteristic is that the specimens are always crisscrossed with red, orange, black, green, white and blue spots, which create that attractive multicolored effect.However, the females have a gray, gold or silver color, with a lighter belly.The tail in both sexes is completely transparent, with colored upper and lower edges.Another sexual difference is found in size, while the male can measure about 2.5 centimeters, the female is much larger, reaching 4.5 centimeters.As with Guppies, they are very easy to hybridize and genetically modify, so you can now find larger Endler Guppy varieties with colas of different shapes and sizes.

Distribution and habitat

Its origin is in the Laguna de Patos, in Venezuela, an area that was part of the ocean, but due to the sandbanks it became a completely independent freshwater lake.This water, when the Endler Guppy was discovered, had a greenish appearance, due to the high concentration of algae. Currently they are difficult to find in the wild, but their distribution would be in the Campoma and Buena Vista lagoons, in northwestern Venezuela.

Aquarium Conditions

The size of the aquarium to keep the Endler Guppy will depend on the number of specimens that we want to have.In principle, an aquarium of 10,57 gallons would be ideal to house one or two males and several females, at least three per male. This proportion is recommended (1 male for three females) due to the constant harassment to which they are usually subjected.The aquarium should maintain a temperature between 75,2ºF and 86ºF, with a pH between 7 and 8.5, with moderately hard water.They will find themselves in a good environment, if we introduce a good number of plants, as well as some floating species, but leaving enough space for them to swim, they are very active.The substrate must be composed of sand or fine gravel.They do not need a very powerful filter, because these fish originate little waste, nor is it recommended that the aquarium have too much current, they like calm waters.They are fairly disease resistant fish as long as the aquarium is between 15 and 20 gallons in size, even so against bacterial diseases or preventively in their adaptation you can use amoxicillin for fish or ampicillin for fish

Tiger variety


They are omnivorous fish. In nature they feed on zoobenthos and detritus, so it is not too complicated to feed them.In the aquarium we can provide them with adequate dry food, as well as mosquito larvae and vegetable foods, such as lettuce leaves (in very small pieces).If we do not provide them with green food, they can consume algae directly from the plants.

Behavior and Compatibility

They are very calm fish with a gregarious nature, so it is convenient to have a small group of fish.In the aquarium they will be perfect with other small species, with which they will not enter into any type of conflict.A good combination would be dwarf corydoras, small rainbow fish, and peaceful tetras.Males are usually quite calm, but females can be territorial. If the group is large enough, this situation is eliminated.Keep in mind that if you mix them with the Guppy (Poecilia Reticulata) they could cross.


The Endler Guppy is very easy to breed in a normal aquarium. If you maintain a community of females and males, you will observe how from time to time there are fry, without having to have done anything to get them.However, if you want to have more control over its reproduction, you should follow the following tips:It is convenient to keep several females for each male. As I mentioned at the beginning, at least three females per male, due to the constant harassment to which they are subjected.The aquarium must be well planted, to facilitate the laying of eggs.The mating ritual begins with the male showing his fins, in a dance that he performs in front of the females.The females can lay their eggs at 23-24 days.It is convenient to have a breeding aquarium prepared. When the female has spawned, we will take her back to the main aquarium, because the first-time females can eat her fry.The female keeps the male’s sperm inside her, so they don’t need to be together once the female Endler Guppy is pregnant.The fry will accept shrimp nauplii or powdered flakes from birth, they grow very fast and in a period of three to five weeks, males can be differentiated from females.
