The Congo Tetra is a vibrant, peaceful fish with shimmering colors, ideal for planted aquariums with plenty of swimming space.
Overview
The Congo Tetra (Phenacogrammus interruptus) belongs to the Alestidae family and is native to the Congo River Basin in Africa. Known for its stunning iridescent colors and long flowing fins, this peaceful species is a favorite among aquarists. It thrives in larger aquariums with dense vegetation and plenty of open space for swimming.
Tank Requirements
Congo Tetras need a minimum tank size of 100 liters. The ideal water temperature ranges between 23-27°C, with a pH of 6.0-7.5 and moderate hardness (GH 5-15). They prefer a planted tank with subdued lighting to mimic their natural habitat. Including plants and driftwood helps create hiding spots and enhances their coloration.
Feeding and Diet
These fish are omnivores and enjoy a varied diet. In the wild, they feed on small insects and plant matter. In an aquarium, they should be provided with a balanced diet of high-quality flake food, small pellets, and occasional live or frozen foods like brine shrimp and bloodworms.
Care and Maintenance
Congo Tetras are relatively hardy but require clean, well-oxygenated water. Regular water changes and a good filtration system are recommended. They are susceptible to stress if kept in inadequate conditions, so maintaining stable water parameters is essential.
Compatibility
Congo Tetras are peaceful and do well in community tanks. They should be kept in groups of at least six to reduce stress and encourage natural schooling behavior. Suitable tank mates include other peaceful fish like rasboras, dwarf cichlids, and small catfish.
Breeding
Breeding Congo Tetras in captivity is possible but requires specific conditions. They are egg scatterers, and spawning is triggered by slightly acidic water and the right temperature. Use a separate breeding tank with fine-leaved plants or a spawning mop, and remove the adults after spawning to protect the eggs.
