Hemigrammus ulreyi, commonly known as Ulrey's tetra, is a species of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins. This species is named in honor of the biologist Albert B. Ulrey. It was originally named Tetragonopterus ulreyi in 1895. ^[2] This species is found in the basins of the Paraguay River and the middle Paraná River in Argentina, Brazil and Bolivia. ^[1]

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]
