Diet
An omnivore that takes small invertebrates from the water column. In aquaria it accepts flakes, micro-pellets and small live or frozen foods (daphnia, brine shrimp, bloodworms).
Compatibility
A peaceful, very active schooling species. Keep a group of at least six in spacious tanks with open swimming areas. Compatible with other active mid-water species; avoid pairing with long-finned slow tankmates as Bloodfin Tetras may nip.
Breeding
An egg-scatterer that spawns at the water surface and lets fertilised eggs sink to the substrate. Adults consume eggs and should be removed after spawning.
