Blue Moscow Guppy (Poecilia reticulata var. Blue Moscow)

The Blue Moscow Guppy (Poecilia reticulata var. Blue Moscow) is a striking and highly prized guppy strain, admired for its deep cobalt-blue body and flowing fins. Guppies (Poecilia reticulata) are naturally native to freshwater streams, rivers, and small ponds in northeastern South America, including the island of Trinidad, Tobago, and parts of Venezuela. In the wild, these waters are warm, slow-moving, and often heavily vegetated, with abundant leaf litter and submerged roots that provide shelter and feeding areas. Guppies have evolved in these environments as adaptable, hardy fish capable of thriving under a range of water conditions.

In the aquarium, Blue Moscow Guppies retain the social behavior and vitality of their wild ancestors. Males display the intense blue coloration along the body and fins, while females are more subdued, showing a pale front half and dusky blue rear. They are peaceful, active swimmers that thrive in groups, exhibiting normal schooling behavior. As livebearers, Blue Moscows give birth to fully formed, free-swimming fry rather than laying eggs, making them highly prolific and engaging for aquarists interested in observing natural reproduction in the home aquarium.

Blue Moscow Guppies are hardy and adaptable, accepting a wide range of diets including high-quality flakes, micro-pellets, and live or frozen foods such as daphnia and brine shrimp. They thrive in slightly alkaline water with temperatures between 74°F and 82°F, and a planted aquarium with moderate hiding spaces and dark substrate will highlight their vivid coloration. True Blue Moscow Guppies with deep, even pigmentation are rare, making each individual a noteworthy addition for hobbyists who value both biology and beauty. These fish ship individually bagged, one fish per bag.
