In the aquarium

This aquarium fish suitable for a community aquarium can reach 5 cm (2 in) in length and does well at temperatures of 21 to 29°C (70 to 85°F).
Breeding

The breeding size is 4 cm (1.6 in). Dr. Herbert R. Axelrod, editor of Tropical Fish Hobbyist Magazine, and Dr. Leonard P. Schultz, retired curator of fishes at the Smithsonian Institution, wrote that the breeding of this species is a problem, since the species is nearly identical to Hyphessobrycon heterorhabdus and is difficult to spawn.
