Overview

Powder-Blue Lampeye (Procatopus gracilis) is a shimmering, peaceful surface-dwelling lampeye that brings brilliant blue color and lively movement to a planted aquarium. Native to West Africa, especially freshwater streams and forest waters in Cameroon and adjacent regions, this species is prized for its delicate beauty, iridescent coloration, and manageable size. Now available for sale UK from Tropical Fish Co, this charming surface-dweller is ideal for the specialist keeper seeking a peaceful, active shoaling species.

Appearance

The Powder-Blue Lampeye typically reaches around 3.5 cm in total length, making it a small and delicate fish. The body is elongated and semi-transparent, with a shimmering powder-blue iridescence that appears to glow under subdued lighting. The eyes are large and reflective, giving the species its "lampeye" common name. The fins are delicate and transparent, often showing subtle hints of color in well-conditioned males. Females are generally more subdued in color. Healthy specimens have bright, clear eyes and smooth, undamaged fins.

Natural Habitat

In the wild, Procatopus gracilis is native to West Africa, especially freshwater streams and forest waters in Cameroon and adjacent regions. These waters are typically soft, warm, and slightly acidic, with muddy or sandy substrates and plenty of aquatic vegetation providing cover. The fish spend much of their time near the surface, feeding on small insects, larvae, and zooplankton. Light levels are low due to the dense forest canopy above.

Aquarium Setup

A well-planted aquarium of at least 75 litres is recommended for a shoal of Powder-Blue Lampeyes. Use a fine, dark substrate and incorporate plenty of live plants such as Java moss, Java fern, Cryptocoryne species, and floating plants to provide cover and subdued lighting. Filtration should be gentle but effective, and a tightly fitting lid is essential, as lampeyes are active jumpers. Subdued lighting and minimal water movement will help the fish settle and display their best colors.

Feeding

The Powder-Blue Lampeye is a microcarnivore with a diet leaning toward carnivore. Offer small live and frozen foods such as daphnia, brine shrimp, mosquito larvae, and quality micro-pellets or flakes daily. Varied, protein-rich meals will enhance coloration and support breeding condition. Feed twice daily in small amounts to maintain excellent water quality.

Behaviour

This lampeye is peaceful, active, and social, constantly on the move near the surface and best kept in a shoal of at least six individuals. When kept in proper numbers, the Powder-Blue Lampeye is confident and displays natural schooling behavior. Males may engage in mild displays, but serious aggression is rare. They occupy the upper levels of the aquarium and are most active during the day.

Tank Mates

The Powder-Blue Lampeye is suitable for a peaceful community aquarium with other small fish. Good tankmates include other small peaceful West African fish, small peaceful tetras, small rasboras, peaceful bottom-dwelling catfish, and snails. Avoid large predatory fish, aggressive cichlids, fin-nipping barbs, large fast-feeding species, and very boisterous tankmates.

Breeding

Breeding the Powder-Blue Lampeye is achievable with careful preparation. This species can be bred in a well-planted species tank with soft to moderately hard water and excellent food quality. Eggs are typically scattered among fine-leaved plants or spawning mops. Adults may eat eggs and fry, so separate breeding and rearing setups are recommended. Fry are tiny and require infusoria or other very small live foods initially.
