Care

The Congo Tetra is a beautiful, active species and is fairly timid and easily frightened. It is very important, therefore, to keep them in groups of at least 6, and preferably more. The tank should be at least 4ft long and include areas of dense planting in order for the fish to feel secure. The water should be clean and well-oxygenated, with a good flow rate. Not to be kept with boisterous, fin-nipping fish, or any tiny fish species.

Feeding

Will accept all types of food. Try to vary the diet with flakes, algae based flakes, slow-sinking pellets, and frozen foods such as mosquito larvae, brineshrimp, Mysis etc.

Breeding

Congo Tetras are challenging to breed. A well-conditioned pair should be added to a separate aquarium that has been set up with soft water and plenty of plant cover. Spawning can be quite an active affair, so the tank should be as long as possible. Many reports suggest that spawning commences when the first rays of the morning sun hit the aquarium, where up to 300 weakly adhesive eggs can be laid. The pair should be removed as soon as spawning has ceased, otherwise they will predate on eggs. Before hatching, the eggs will develop a hard shell. After 5-7 days (dependent on water temperature) the eggs will hatch and the young fry can be offered infusoria and baby brineshrimp.
