The Red Belly Tetra (Hyphessobrycon pyrrhonotus) is a striking freshwater fish known for its shimmering silver body and distinctive reddish hue on its underside, especially vivid in males during breeding. These active, peaceful schooling fish thrive in groups of six or more and do best in well-planted tanks that mimic their natural Amazonian habitat, with subdued lighting and dark substrates to enhance their colors. They prefer stable, clean water with gentle flow and enjoy a varied diet of high-quality flakes, micro pellets, and live or frozen foods like daphnia and brine shrimp. Ideal for community aquariums, Red Belly Tetras are hardy but appreciate consistent maintenance and good water quality to stay vibrant and healthy.
