Quick Overview Hailing from the fast-flowing river basins of Africa, the Congo Tetra (Phenacogrammus interruptus) is the definition of eye candy for the freshwater hobby. Unlike most small tetras, the Congo Tetra reaches a substantial and robust size of about 3 to 3.5 inches. They feature large, reflective scales that shift beautifully through shades of neon blue, fiery orange, gold, and red depending on how the light hits them. Mature males develop spectacular, elongated dorsal fins and a unique, feather-like center extension on their tail fins, making them a breathtaking centerpiece option.
Tank Requirements & Local Care Tips

-
Temperament: Peaceful but active (Excellent with other robust community fish like peaceful Cichlids, larger Rasboras, Corydoras, and Rainbowfish; avoid tiny shrimp as they may become a snack)

Bacolod Hobbyist Tip: Juvenile Congo Tetras often look a bit dull and silvery when they first arrive at a pet shop, but don’t be fooled! As they mature and settle into a proper aquarium, their breathtaking rainbow colors and long fins will quickly burst to life. To truly showcase their metallic shimmer under your aquarium lights, we highly recommend a backdrop of lush green live plants and dark gravel or aquasoil. Stop by our store here in Bacolod to pick up premium, high-protein color-enhancing flakes, heavy-duty filtration systems to manage their active bioload, and a gorgeous school of Congo Tetras!
