Guppy aquarium fish, perhaps, are known even to those who are not keen on aquarism. Many people first of all get an aquarium with guppies, and only then they seriously take a great interest in other species.

Homeland fish

The homeland of the guppy fish is the northern part of South America. But in order not to sound so abstract, it is often more specifically said that their homeland is the islands of Barbados and Trinidad, which are located not far from the South American continent.

But the fish began to be massively bred in areas where malaria mosquitoes were found (fish eat their larvae), as a result of which the fish spread and the title of one of the most popular stuck to them, so the guppy is remembered only for history.


They got their name from their discoverer Robert Guppy in 1866, who discovered them on the island of Trinidad.

They live near the shores in clear waters, but also brackish, they do not like salty sea water. By the way, it is for this reason that the water should not be sea or salt, this is a freshwater fish, maximum salted water.

Guppies in nature are small and not protected. Males have a brighter color, which somehow protects them from predators. The male is smaller than the female; it grows about 5 cm in length (the males usually grow shorter in length).
