Blue Limia (Poecilia melanogaster) — 3-4cm

Overview

Blue Limia (Poecilia melanogaster), also known as the Black-Bellied Limia, is a rare, peaceful Jamaican livebearer with striking blue-black coloration that thrives in clean, hard, well-oxygenated water. Native to Jamaica, where it inhabits fast-flowing streams, this species is prized for its unique appearance, peaceful nature, and rarity in the modern aquarium hobby. Now available for sale UK from Tropical Fish Co, this uncommon livebearer is ideal for the specialist community aquarium keeper.

Appearance

The Blue Limia typically reaches around 4 cm in total length, making it a small livebearer. The body is robust and deep-bodied, with a pale silver or blue base color marked with distinctive dark blue-black markings, especially on the belly and flanks. Males are generally more colorful, showing more intense blue-black coloration, especially during courtship displays. Females are larger, more robust, and less colorful. Healthy specimens have bright, clear eyes and smooth, undamaged scales.

Natural Habitat

In the wild, Poecilia melanogaster is native to Jamaica, where it inhabits fast-flowing streams with clean, well-oxygenated, and moderately hard water. These habitats are characterized by rocky substrates, strong currents, and plenty of algae and biofilm growth on submerged surfaces. The fish spend much of their time grazing on aufwuchs and microorganisms, and are adapted to life in flowing water.

Aquarium Setup

A well-filtered aquarium of at least 60 litres is recommended for a small group of Blue Limias. Use a fine gravel or smooth stone substrate and incorporate smooth rocks, driftwood, and robust live plants to provide visual interest and grazing surfaces. Ensure good filtration and moderate water movement to reflect the species' stream habitat. A secure lid is advisable, as livebearers can jump when startled. Maintain stable, warm water with hard, alkaline pH.

Feeding

The Blue Limia is an omnivore and thrives on a varied diet. Offer high-quality flake or micro-pellets as a staple, supplemented with algae-based foods, blanched vegetables, and small frozen or live foods such as daphnia and brine shrimp. Feed twice daily in small amounts to maintain excellent water quality.

Behaviour

This livebearer is peaceful, active, and social, constantly on the move and best kept in a small group. Males will court females continuously, but serious aggression is rare. When kept in proper numbers, the Blue Limia is confident and displays natural behavior. They occupy all levels of the aquarium and are most active during the day.

Tank Mates

The Blue Limia is suitable for a peaceful community aquarium with other hard-water fish. Good tankmates include other peaceful livebearers, small peaceful community fish, and peaceful snails. Avoid large aggressive cichlids, fin-nipping fish, predatory fish, very boisterous species, and large shrimp-eating fish.

Breeding

Breeding the Blue Limia is achievable with careful preparation. This is a livebearer that may breed in captivity under stable, warm, hard, alkaline water conditions. Provide dense planting or spawning cover. Fry are free-swimming at birth and should be protected from adults if you want to raise them.
