In the aquarium
This aquarium fish suitable for a community aquarium can reach 5 cm (2.0 in) in length and does well at temperatures of 21 to 29 °C (70 to 84 °F).[3]
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.[3]
