The Bleeding Heart Tetra is native to the upper Amazon River basin on the borders between Brazil, Colombia and Peru. It lives amongst dense vegetation along the banks of small and medium-sized streams.

There is noticeable sexual dimorphism in its fins. Males have a longer and more curved dorsal fin than females and their anal fin is pointed. Another difference is colour, with the male's shades being more intense than those of the female.

It is a quiet and very sociable species that lives in large shoals in which the dominant individuals remain in the central area surrounded by other less important individuals so that they are protected from possible attacks.

Clutches, which are laid on leaves, consist of 300-400 eggs that hatch after 24-36 hours.
