Moscow Green 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 — with green being one of the rarer shades.

🌈 Appearance & Distinctive Features

• 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 — especially in males — giving a regal and eye-catching look. Genki Aquatics

• Size:

  • Males: ~1.5–2 inches (4–5 cm)

  • Females: ~2–2.5 inches (5–6 cm) Aquarium Fish Source+1

💧 Tank Setup & Water Conditions

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: ~22–28 °C (72–82 °F) Splashy Fish

• pH: ~6.8–7.8, with a sweet spot close to neutral (~7.0–7.2). Splashy Fish

• Environment: Well-planted tanks with open swimming areas — live plants like Java moss, Anubias, or Hornwort offer shelter and reduce stress. Marlin Aqua

Lighting: Good aquarium lighting accentuates the guppies’ metallic sheen. FishyHub

🍽️ Diet & Nutrition

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 (2–3× a day) keep them active and prevent overfeeding. Marlin Aqua

🧠 Temperament & Tankmates

• Behavior: Peaceful, social, and active swimmers — 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

🐣 Breeding & Life Cycle

One of the joys of guppy keeping is watching them breed:

• Livebearers: Females do not lay eggs — they give birth to live fry. Aquarium Fish Source

• Gestation: ~25–30 days before fry are born. Marlin Aqua

• Fry Care: Provide hiding plants or use a breeding tank/box so adults don’t eat fry. Feed fry crushed flakes or baby brine shrimp. Aquarium Fish Source

• Ratio Tip: A common recommendation is ~1 male to 2–3 females to reduce stress on females. Marlin Aqua

🩺 Health & Common Issues

Moscow Green Guppies are generally hardy, but like all guppies, they’re susceptible to:

• Ich (white spot disease) — can be prevented with stable water conditions. Marlin Aqua

• Fin Rot — often from poor water quality — treat with improved maintenance and medicines. Marlin Aqua

• Parasites — 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.

📅 Lifespan

With proper care and a good environment, Moscow Green Guppies usually live 2–3 years
