The Congo Tetra (Phenacogrammus interruptus) is a moderate-care, peaceful species from Congo basin. Adults reach roughly 3", so plan on a minimum tank of 30 gallons. Keep the water between 73–82°F with a pH of 6–7.5. This is a schooling fish — keep a group of at least 6 so it feels secure and colors up. Its long fins make it a target for known fin-nippers. As an omnivore, it does best on a varied diet appropriate to its feeding style.
