Chilli Mosaic Guppy M/F

Overview

The Fancy Guppy (Poecilia reticulata) is one of the most popular aquarium fish worldwide, available in an enormous range of colours, tail shapes, and patterns. Active livebearers that breed readily — ideal for beginners but require attention to water quality due to sensitivity to nitrates.

Water Parameters

• Temperature: 22–28°C (72–82°F)
• pH: 7.0–8.0 (prefer slightly alkaline)
• Hardness: 8–20 dGH (moderately hard; soft water causes osmotic stress)
• Note: Very sensitive to nitrates — keep below 20 ppm

Tank Setup

• Minimum tank size: 40 litres for a trio (1M, 2F)
• Decor: Planted with open swimming space; floating plants for fry cover
• Cover: Tight-fitting lid essential — they jump

Diet

• Base: High-quality flake, micro pellets
• Treats: Frozen bloodworms, brine shrimp, blanched vegetables
• Frequency: 2 small meals daily

Temperament & Tank Mates

• Temperament: Peaceful, active, social
• Best companions: Other peaceful livebearers, corydoras, small tetras, dwarf shrimp
• Avoid: Fin-nippers, large predatory fish
• Note: Males may pester females — keep 1M:2F+ ratio

Breeding

• Difficulty: Very easy — they breed constantly
• Process: Give birth to free-swimming fry; 21–30 day gestation
• Fry survival: Adults eat fry — provide dense floating plants or breeding box
• Population control: Keep single sex or expect rapid population growth

Common Issues

• Nitrate sensitivity — excellent filtration and regular water changes essential
• Finnibalism can occur in small tanks or with aggressive tank mates
• Males stress females with constant chasing — maintain 1M:2F+ ratio
• Lifespan: 1–3 years
