Red Belly Tetra - Hyphessobrycon erythrostigma

Red Belly Tetras (Hyphessobrycon erythrostigma), also called Bleeding Heart Tetras, have a silver body with a distinctive red mark near the gills. Plan a suitable freshwater community around their adult requirements.

Size and Lifespan

Red Belly Tetras typically reach lengths of 6–8 cm, making them well-suited for medium to large aquarium setups. With attentive care, they have a lifespan of 5–7 years, offering enduring appeal to hobbyists. Their moderate size and resilient disposition make them an excellent choice for both novice and seasoned aquarists.

Suitable Tank Mates

Red Belly Tetras coexist well with peaceful fish species, making them suitable for community aquariums. Compatible tank mates include Corydoras, Rasboras, Gouramis, and similarly sized tetras. They should not be kept with aggressive or predatory fish, as their gentle temperament makes them vulnerable. Providing an appropriately designed habitat helps maintain their health and vitality

Caring 

Red Belly Tetras flourish in aquariums of 100 litres or more that combine open swimming spaces with live plant cover. They thrive at temperatures between 23°C and 28°C and prefer a pH level from 6.0 to 7.5. Consistent water changes and effective filtration are crucial to sustain optimal water conditions. Using a dark substrate and soft lighting accentuates their vibrant colours, making them visually striking within the tank.

Feeding 

Red Belly Tetras are omnivorous and benefit from a diverse diet. A base of premium flakes or micro-pellets is ideal, complemented by live or frozen options such as bloodworms, brine shrimp, or daphnia to increase vitality and intensify their colouration. Occasionally offering blanched vegetables like zucchini or spinach supplies extra nutrients that promote their general well-being.
