Information describing the reproduction of bleeding heart tetras comes mostly from studies in aquaria. Reproduction is through external fertilization. Females often reject or do not respond to mating attempts of males in captivity. Spawning begins with vigorous swimming among dense vegetation and is followed by mates pressing their sides together. Eggs are released after brief quivering. Eggs then attach to vegetation or fall to the bottom.
Mating System: polygynandrous (promiscuous)
Little is known about reproduction in bleeding heart tetras in wild habitats.
Average time to hatching: 30 hours.
Average time to independence: 5-6 days.
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (External ); oviparous
There does not seem to be parental involvement with the young after the eggs are laid.
Parental Investment: no parental involvement; pre-fertilization (Provisioning, Protecting: Female)
