Red & Blue Colombian Tetra
Red & Blue Colombian Tetra(Hyphessobrycon columbianus) is one of the most dramatically colored tetras available — a large, robust Hyphessobrycon with vivid electric blue iridescence on the upper body and vivid red fins, creating one of the most striking two-element color combinations in the tetra family. Described in 2000, relatively recently added to the hobby.

Native to the Acandí River drainage of northwestern Colombia — the Darién region near the Panamanian border. Described in 2000.
Keep in groups of at least 8. The blue body and red fins are most vivid in well-conditioned fish in moderately soft water. Males are slightly larger and more vividly colored than females.
One of the finest tetras for a show aquarium — the blue-and-red combination at this scale is among the most visually impactful of any schooling fish.
