Lampeye Congo Tetra – A Rare African Tetra with Brilliant Reflective Eyes
The Lampeye Congo Tetra (Phenacogrammus aurantiacus) is a beautiful and relatively uncommon African freshwater fish admired for its shimmering body, distinctive reflective eyes, and graceful swimming behaviour.
Native to the Congo Basin in Central Africa, this attractive tetra displays subtle metallic colours that can shift under aquarium lighting, creating an elegant appearance in natural freshwater aquascapes.
Its reflective eyes are a particularly striking feature, giving the fish its popular "Lampeye" name.
Unlike the more familiar Congo Tetra (Phenacogrammus interruptus), this species offers a different appearance and is an interesting choice for aquarists seeking less commonly available African characins.
Lampeye Congo Tetras are best maintained in groups within spacious, well-established aquariums featuring aquatic plants, driftwood, shaded areas, and open swimming space.
With their distinctive appearance and fascinating group behaviour, these African tetras make an appealing addition to carefully maintained tropical freshwater aquariums.
