Hemigrammus pulcher is a semi-popular aquarium species, also known as the pretty tetra, garnet tetra or black wedge tetra. In the wild, the species is found near Iquitos in the Peruvian Amazon, and probably also in Brazil and Colombia.
Breeding is difficult, as parents must be prevented from eating their own eggs, and require soft, acidic water. Eggs usually hatch within 20–24 hours. The tetra will accept most high quality flake foods. They do best in groups of 6 or more.
