BLUE MOSCOW GUPPY

The Blue Moscow Guppy (Poecilia reticulata) is one of the most striking and elegant guppy strains, known for its deep, solid metallic blue coloration that covers the entire body and tail. Unlike patterned guppies, the Blue Moscow displays a rich, uniform tone—ranging from cobalt to midnight blue—that shimmers under aquarium lighting, giving it a sleek and luxurious appearance. Selectively bred for both color intensity and fin quality, this guppy variety is a favorite among collectors and aquascaping enthusiasts for its beauty and refinement.

Adult males typically grow to about 1.5 inches (3.5–4 cm) and showcase the strongest coloration, while females reach up to 2.5 inches (6 cm) and have a paler, silver-blue sheen. Together, they create a calm yet dazzling presence in any freshwater setup.

Ideal water parameters:
Temperature: 72–82°F (22–28°C)
pH: 7.0–8.0
Hardness: 8–20 dGH

Tank setup:
Blue Moscow Guppies thrive in clean, well-filtered aquariums of 10 gallons or larger with stable water conditions. Use moderate lighting and a dark substrate to accentuate their rich blue tones. Provide a mix of open swimming areas and plants such as Anubias, Java Fern, or Water Sprite for cover and fry protection. Females give birth every 4–6 weeks, and dense vegetation helps protect the fry from predation.

Diet:
They are omnivorous and benefit from a varied, high-quality diet. Feed them fine flakes or micro-pellets as a staple, and supplement with frozen or live foods such as brine shrimp, bloodworms, and daphnia. Spirulina flakes or blanched vegetables like zucchini and spinach help enhance coloration and maintain long-term health.

Temperament and tankmates:
Blue Moscow Guppies are peaceful, active, and social fish that do well in community aquariums. Ideal tankmates include platies, mollies, swordtails, endlers, tetras, rasboras, and corydoras. Avoid fin-nipping or aggressive species that may damage their flowing fins.

In summary, the Blue Moscow Guppy is a graceful and visually stunning livebearer that embodies sophistication and beauty. Its solid blue body, shimmering metallic finish, and calm demeanor make it an excellent centerpiece for planted or community aquariums—perfect for aquarists who appreciate elegance, color, and easy care in one exceptional fish.
