The Story
🌈 Congo Tetra Fish – Iridescent Beauty from Central Africa
Bring a splash of shimmering elegance to your freshwater aquarium with the Congo Tetra Fish (Phenacogrammus interruptus). Native to the slow-moving rivers of the Congo Basin, these peaceful schooling fish are prized for their flowing fins, rainbow-like iridescent body, and graceful swimming patterns. When kept in a well-maintained planted tank with a group of six or more, their full colors and personalities truly shine.
Congo Tetras are an ideal choice for community tanks, as they are peaceful, hardy, and compatible with a variety of other tropical species. Their subtle glow under soft lighting makes them a favorite among aquascapers and collectors alike.
