Natural habitat
The Congo Tetra originates from the river systems of the Democratic Republic of the Congo, where it inhabits areas with dense vegetation and moderate water flow. These conditions help the species thrive and exhibit their vibrant colors, particularly in the presence of both male and female fish.
Where they are found
Found predominantly in the Congo River basin, this species adapts well to various aquatic environments as long as conditions are kept stable. They can be found in both slow-moving waters with rich plant cover and in slightly swifter currents.
Aquarium care
To care for Congo Tetras, maintain a spacious aquarium with a minimum length of 120 cm and a water temperature between 23°C and 26°C. Filter systems should provide a gentle flow to mimic their natural habitat. Provide plenty of plants and hiding spots to reduce stress and help them feel secure. Regular water changes are essential for keeping optimal water conditions, including a pH level between 6.0 to 8.0 and a hardness of 5 to 20 dGH.
Feeding
Congo Tetras are not picky eaters and thrive on a varied diet. Offer a mix of flakes, granules, and frozen foods, such as brine shrimp and mosquito larvae. Regular dietary diversity will promote good health and vibrant coloration.
Compatibility
Congo Tetras are peaceful community fish and are best kept in groups of at least six. They should not be housed with aggressive or fin-nipping species, and care should be taken when placing them with long-finned fish as they may become targets. Overall, they coexist well with other non-aggressive species in a community tank.
Breeding
Breeding Congo Tetras can be challenging and typically requires a separate breeding tank with soft water and ample plant cover. A well-conditioned pair may spawn in the early morning, laying up to 300 eggs. It’s crucial to remove the parents after spawning, as they may eat the eggs. The eggs usually hatch within 5 to 7 days, during which time the fry can be fed infusoria and baby brine shrimp.
