Hemigrammus ulreyi, commonly known as Ulrey's tetra, is a Paraguayan tropical aquarium fish from the family Characidae named in honor of the biologist Albert B. Ulrey. It was originally named Tetragonopterus ulreyi in 1895.[1]
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).[2]
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.[2]
