Food and feeding

Blue Neons are micro-predators that thrive on a diet of small live or frozen foods such as brine shrimp, daphnia, and mysis. While they will accept quality flakes or micro-pellets, regular inclusion of protein-rich live foods helps bring out their best coloration and maintain good condition.

Origin

Paracyprichromis nigripinnis originates from Lake Tanganyika, Africa, where it inhabits rocky slopes and open water zones near cliffs. These fish typically hover in midwater schools close to the rockwork.

Sexing

Males usually grow slightly larger and exhibit more intense iridescent blue coloration, especially in the fins. Females are a little smaller and less vividly colored, but both sexes are attractive.

Breeding

This species is a maternal mouthbrooder. The female carries the eggs in her mouth after spawning on vertical rock surfaces or slates. A typical clutch numbers around 10–12 eggs. Fry are released after several weeks and are large enough to feed on newly hatched brine shrimp or finely crushed flakes.

Lifespan

The expected lifespan of Blue Neons is about 5–8 years with proper care and stable water conditions.

Tank requirements

• Tank size: 150 L for a small group.
• Aquascape: vertical rock structures, caves, and open swimming space.
• Water: pH 8.0–8.5, moderately hard to hard water, 23–25 °C.
• Lighting: subdued or moderate, which mimics their natural habitat and enhances their colors.

Tankmates

They are peaceful schooling fish best kept in groups of six or more. Compatible with other Lake Tanganyika species such as Neolamprologus and Cyprichromis, but avoid keeping them with overly aggressive cichlids or very large predators. Their slow, hovering swimming style makes them vulnerable to fast, boisterous fish.

Short description

Known as one of the most elegant Tanganyikan cichlids, the Blue Neon glides in the water at unique angles, often swimming head-up or diagonally. Their neon blue sheen and calm schooling behavior make them a striking addition to a well-maintained Rift Lake aquarium.
