Brycinus longipinnis is a spectacular schooling tetra from West Africa with luxurious elongated fins, an undemanding and peaceful fish for community tanks.
Overview
Brycinus longipinnis is one of the most visually striking members of the Alestidae family, native to tropical rivers and streams of West Africa. In the wild, this species inhabits river basins of Nigeria, Ghana, Sierra Leone, and Liberia, where it occupies areas with moderate current, abundant vegetation, and shaded banks.
The fish reaches 12–15 cm in length and immediately draws attention with its elongated fins, particularly pronounced in males. The dorsal and anal fins of mature males develop a luxurious flowing form, which earned the species its common name — the long-finned tetra. The body is silvery with an olive tint on the back and a subtle golden sheen along the flanks. A dark-edged caudal fin gives the fish a polished appearance. Females are more modestly colored and have shorter fins. Lifespan in the aquarium is 5–8 years.
Brycinus longipinnis is an active schooling fish that prefers the middle and upper water layers. In a group, these tetras display impressive synchronized swimming, and males periodically spread their long fins, creating a truly captivating spectacle. The species is closely related to the African red-eyed tetra and the Congo tetra, with which it coexists beautifully in the same aquarium.
Tank Requirements
A tank of at least 120 liters is required to house a school of Brycinus longipinnis. These are large and active fish that need ample space for free swimming. Optimal water parameters: temperature 22–28 °C, pH 6.0–7.5, hardness GH 5–15.
The aquarium should be equipped with a tightly fitting lid — like many African tetras, these fish are prone to jumping, especially when stressed or during the acclimation period. This is an important detail that should not be overlooked.
Decor is best arranged in the style of a West African biotope: dark fine substrate, driftwood and branches, densely planted areas along the sides, and a spacious open swimming zone in the center. Floating plants (water lettuce, salvinia) will help diffuse overhead light and create a sense of security, encouraging the fish to feel more confident and display better coloration. Water flow should be moderate, replicating natural conditions.
Feeding and Diet
In the wild, Brycinus longipinnis is an omnivorous species that feeds on insects that fall onto the water surface, small invertebrates, larvae, and plant matter. In the aquarium, these fish are undemanding and readily accept most foods.
The dietary foundation should consist of high-quality flakes or granules for tropical fish. To maintain health, vibrant coloration, and proper fin development, regularly supplement the menu with live or frozen foods: bloodworms, brine shrimp, daphnia, and glassworms. These tetras primarily take food from the water surface and mid-water column — sinking tablets are less suitable for them.
Feed twice daily in small portions that the fish can consume within 2–3 minutes. An occasional fasting day once a week will benefit their digestion and overall condition.
Care and Maintenance
Brycinus longipinnis is a hardy species with a care level of 2 out of 5, suitable even for aquarists with minimal experience. The key to successful keeping is stable water parameters and regular tank maintenance.
Weekly water changes of 25–30% of the total volume are essential. Filtration should ensure good water quality while creating moderate flow. Both an external canister filter and a powerful internal filter will work well. Monitor ammonia and nitrate levels — nitrates should not exceed 25 mg/l. Aeration is recommended, as these fish naturally inhabit well-oxygenated waters.
Long-finned tetras must be kept in schools of at least 6–8 individuals. In a small group, the fish become nervous, lose their coloration, and may display shy behavior. In a larger school, they swim confidently and actively, showcasing the full beauty of their luxurious fins.
Compatibility
Brycinus longipinnis is a peaceful schooling fish with an aggression level of 2 out of 5, making it an excellent choice for a community tank with similarly sized tankmates. Thanks to its calm temperament and moderate size, this tetra is compatible with a wide range of species.
Excellent companions include Congo tetras, Arnold's red-eyed tetras, yellow-tailed Congo tetras, bronze corydoras, bristlenose plecos, and kribs. They also coexist well with other peaceful medium-sized fish such as rainbowfish, larger danios, and barbs.
Avoid housing them with very small fish (neons and micro species may be perceived as prey) or with large aggressive cichlids that will intimidate the school. It is also best to avoid slow-moving species with long flowing fins — the active long-finned tetras may pester them.
Breeding
Breeding Brycinus longipinnis in the aquarium is achievable, though it requires some preparation — difficulty is rated 3 out of 5. For spawning, prepare a separate tank of 40–60 liters with soft, slightly acidic water: pH 6.0–6.5, temperature 26–28 °C, GH no higher than 5.
Long-finned tetras are egg scatterers and show no parental care. Line the bottom of the breeding tank with fine-leaved plants (Java moss, cabomba) or a synthetic mesh to protect the eggs from being consumed by the parents. Lighting should be subdued. Condition the breeding pair with generous live food for 1–2 weeks before spawning.
Spawning typically occurs in the morning hours. Once egg-laying is complete, the adults must be removed immediately, as they will actively eat their own eggs. Incubation lasts 24–36 hours, and the fry begin free-swimming after 3–4 days. First food should be infusoria and brine shrimp nauplii. As the fry grow, transition them to crushed flakes and microworms. Fry grow relatively quickly provided they receive frequent water changes and quality feeding.
