A gregarious species which positions itself near the surface between the stems of emerging plants. It is frequently found in stagnant waters. They are generally peaceful, but when there are too many of them during feeding, they bite each other's fins (Ref. 12225). Feeds on worms, crustaceans, insects and plants (Ref. 7020). Oviparous (Ref. 205). This species is part of a complex of `blood' tetras, hybrids of which are commonly offered in the aquarium trade. Aquarium keeping: aggressive; in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Oviparous (Ref. 205). In captivity, spawning is preceded by vigorous driving by the male during the early hours of the day and eggs mostly sink to the bottom (Ref. 7020).
