The bleeding heart tetra is a hardy, peaceful, schooling species that should be kept in groups of six or more. It does extremely well when kept with other peaceful fishes, such as Megalamphodus, Corydoras and Nannostomus species.
Bleeding heart tetras prefer a somewhat dark environment. They are best housed in a tank that contains several bunches of large plants (either live or plastic) in back and on the sides of the tank, with smaller plants in the front, leaving plenty of open space for swimming. A layer of floating plants to diffuse the light is also suggested. Pay strict attention to water quality.
Most tetras are carnivores that are specialized for eating small aquatic insects and the larvae of terrestrial insects. In the aquarium they will do quite well on commercial flake, frozen or freeze-dried foods. Be sure to vary their diets between dry foods and small live foods, such as bloodworms, glass worms, brine shrimp and Tubifex worms.
Bleeding Heart Tetras are typical egg-scattering tetras that require a larger-than-normal breeding aquarium (20 gallons or larger) to successfully mate. They can be sexed by the extended dorsal and anal fins and brighter colors of the male, but it is still best to buy a group and let them pair off, as they seem to breed more readily when they can choose their mates.
