Guppies Species


The Guppy fish, or Guppies, are a group of livebearers in the family Poeciliidae. They are very closely related the Swordtails, Platies and Mollies. There is only one specie of guppy in the aquarium trade, Poecilia reticulata, however there are many closely related species of guppy like fish that are often bred with guppies! Guppies have been bred in captivity for many decades, and there are now hundreds of strains found all over the world. They are very popular aquarium fish due to their bright colors, array of patterns and sociable nature.

Guppies come in a wide variety of colors, with many different strains being sold in pet shops. Guppies can be found with many different fin types, as well as countless different colors and patterns. The most commonly encountered tail type in pet stores is the delta tail guppy. Other commonly encountered fin types include the swordtail guppy and veiltail guppy.


Guppies are native to the northeast of South America where they are found in many different river drainages throughout their native region. However, they have been introduced in drainages throughout the world as a means of mosquito control. Guppies are sexually dimorphic, with male guppies being much smaller and brighter in color than the larger more drably colored female guppies. Male guppies typically reach 1.4” (3.5 cm) while females can reach 2.4” (6cm).

Like all livebearers in the Poeciliidae family, guppies give birth to live young. Male guppies have a modified anal fin that is used for mating. Female guppies can give birth to live young approximately every thirty days, with some strains giving birth to upwards of 100 fry!

Captive Care

Guppies can make great aquarium inhabitants, provided their husbandry needs such as diet, water quality and tank space are met.

Guppies can tolerate a wide range of water temperatures, and can do well at a range of 64F (17C) to 84F (28C), however they tend to prefer the middle of that range.

Guppies do well in community tanks, provided they are not kept with large or overly aggressive fish. Many fish will pick at the tails of fancy male guppies, so avoid boisterous fish. As with most live bearers, it is generally suggested to keep guppies at a ratio of two to three females for every male. The males can become quite boisterous during courtship, so having several females helps spread out the males attentions.

What People Say

After feeding my seahorses your mysis for about 3 months; they are fat and happy!!! they give me baby seahorses (at least 300 ) each 14 days... So I'm very satisfied of your mysis.The frozen mysis is about 70 per cent of their diet.

I am keeping these Indian mudskippers -- very cute -- about 3-4 inches long. I've been feeding them frozen bloodworm, and decided to try them on mysis. I feed them in a "shallows" in the 150 I have set up for them. The minute the mysis hit the water they were on it, frozen and all. They gorged until their little bellies were almost bursting. I have yet to see an aquatic creature that does not go absolutely nuts over PE Mysis.
