Colombian Tetra - Hyphessobrycon columbianus

The Colombian Tetra (Hyphessobrycon columbianus) is a bold, colourful schooling fish that brings instant energy and movement to any community aquarium. With their metallic blue bodies, bright red fins, and shimmering highlights under good lighting, these tetras create a striking display that stands out even in heavily planted tanks.

Hardy, active, and full of personality, Colombian Tetras thrive in medium?sized aquariums with plenty of open swimming space. Keep them in groups of six or more to encourage tight schooling and reduce any occasional fin?nipping. Their colours intensify beautifully with a darker substrate, clean water, and a varied diet — making them a favourite for aquarists who want maximum visual impact with minimal effort.

If you’re after a lively, eye?catching fish that instantly brightens a community tank, the Colombian Tetra delivers every time.
