Overview
The Moscow Blue Guppy is a prized line-bred strain in which males are a solid, deep metallic blue from nose to tail, the colour shifting between violet and turquoise as the fish moves. Guppies originate from Trinidad and northern South America, though aquarium strains are farm-raised. Active, peaceful and easy to keep, they suit beginners and any calm community aquarium.
- Adult Size: Around 3–4 cm (1.5 in) for males; females larger at 5–6 cm (2–2.5 in)
- Lifespan: 2–4 years
Origin
- Native to: Trinidad, Venezuela, Guyana and northern Brazil
- Habitat: Warm, slow streams, ditches and ponds, often hard water
Feeding
- Diet: Omnivorous, with a strong appetite
- Preferred Foods: Quality flake, micro pellets, daphnia, brine shrimp, bloodworm, spirulina flake
- Feeding Habits: Small amounts twice daily; include vegetable matter for colour; live foods bring out the best colour and fin growth
Tank Mates
- Best with: Platies, small tetras, rasboras, corydoras, dwarf shrimp and other calm community fish
- Avoid: Fin-nippers such as tiger barbs, large or predatory fish, bettas
Aggression & Behaviour
- Temperament: Peaceful and sociable
- Territoriality: None; males spar harmlessly and chase females constantly
Experience Level
- Difficulty: Beginner
- Challenges: Sensitive to poor water quality and sudden parameter swings; farmed strains can be delicate; stable, well-filtered water is essential
Water Parameters
- Water Type: Freshwater, hard and alkaline
- Temperature: 22–28°C (72–82°F)
- pH: 7.0–8.0
- Hardness: 10–20 dGH
- Flow: Slow
- Tank Size: Minimum 40 litres for a small group; larger is better
Final Notes
The solid Moscow colouring is a recessive trait, so mixing with other guppy strains will produce patchy offspring; keep the line pure if you plan to breed. Male-only groups avoid fry altogether, otherwise keep two or three females per male and expect monthly broods. Guppies jump, so fit a tight lid. A stunning, low-maintenance showpiece for a peaceful tank.
