Poecilia reticulata
Also known as: Guppy
The Moscow Green Guppy is a selectively bred variety of the common guppy (Poecilia reticulata), developed for its striking emerald-green, metallic color and elegant appearance. It comes from the broader Moscow line of guppies, which are known for solid, intense body colours and graceful fins β with green being one of the rarer shades.
Coloration: Deep, vibrant emerald green covering the body and fins. In the right light, the scales shimmer with metallic iridescence that can reflect hints of blue or gold. Splashy Fish
Body Shape: Compact and streamlined like other guppies, with males being slightly sleeker.
Fin Structure: Often elegant, flowing fins β especially in males β giving a regal and eye-catching look. Genki Aquatics
Size:
Males: ~1.5β2 inches (4β5 cm)
Females: ~2β2.5 inches (5β6 cm) Aquarium Fish Source+1
This bold, mono-chromatic colouring and graceful appearance make the Moscow Green Guppy a standout among guppy varieties. Splashy Fish
A proper aquarium setup helps this variety thrive:
Tank Size: Minimum 10 gallons (~40 L), larger preferred for active schooling and breeding. Aquarium Fish Source
Temperature: ~22β28 Β°C (72β82 Β°F) Splashy Fish
pH: ~6.8β7.8, with a sweet spot close to neutral (~7.0β7.2). Splashy Fish
Environment: Well-planted tanks with open swimming areas β live plants like Java moss, Anubias, or Hornwort offer shelter and reduce stress. Marlin Aqua
Lighting: Good aquarium lighting accentuates the guppiesβ metallic sheen. FishyHub
Moscow Green Guppies are omnivorous and thrive on a varied diet:
Base Diet: High-quality flake or pellet foods designed for guppies. Aquarium Fish Source
Protein Boosters: Occasional live/frozen foods such as brine shrimp, daphnia, and bloodworms. Splashy Fish
Color Enhancers: Spirulina flakes and plant matter like blanched zucchini can enhance coloration. Marlin Aqua
Feeding Tips: Multiple small feedings (2β3Γ a day) keep them active and prevent overfeeding. Marlin Aqua
Behavior: Peaceful, social, and active swimmers β ideal for community freshwater tanks. Splashy Fish
Compatible Tankmates: Non-aggressive species like tetras, rasboras, platies, mollies, corydoras, and small shrimp. Splashy Fish+1
Caution: Avoid aggressive fish (e.g., cichlids, tiger barbs) that might stress them or nip fins. Marlin Aqua
One of the joys of guppy keeping is watching them breed:
Livebearers: Females do not lay eggs β they give birth to live fry. Aquarium Fish Source
Gestation: ~25β30 days before fry are born. Marlin Aqua
Fry Care: Provide hiding plants or use a breeding tank/box so adults donβt eat fry. Feed fry crushed flakes or baby brine shrimp. Aquarium Fish Source
Ratio Tip: A common recommendation is ~1 male to 2β3 females to reduce stress on females. Marlin Aqua
Moscow Green Guppies are generally hardy, but like all guppies, theyβre susceptible to:
Ich (white spot disease) β can be prevented with stable water conditions. Marlin Aqua
Fin Rot β often from poor water quality β treat with improved maintenance and medicines. Marlin Aqua
Parasites β quarantine new fish before introducing them to the main tank. Marlin Aqua
Consistent water quality, regular partial water changes, and careful observation go a long way in keeping them healthy.
With proper care and a good environment, Moscow Green Guppies usually live 2β3 years
