[ 33 ] [ 30 ] The fish are raised in a facility in Panama with physical barriers and geographical containment such as river and ocean temperatures too high to support salmon ...
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.
