Hemigrammus pulcher is a semi-popular aquarium species, also known as the pretty tetra, garnet tetra or black wedge tetra.[1] In the wild, the species is found near Iquitos in the Peruvian Amazon, and probably also in Brazil and Colombia.[1]
Physical Appearance
The H. pulcher has a pale-lemon background color with a black area on the flanks, up to the caudal penduncle.[2] Under subdued lighting, the H. pulcher's body appears iridescent.[2] It grows up to 4 cm. (1.5 in).[2]
Males can be distinguished from females through the shape of the swim bladder, which can be seen through the fish's semi-transparent body.[2] In males, the swim bladder is pointed, while in females, the swim bladder is rounded.[2]
In captivity
Aquarists keep this fish in water with temperatures ranging from 23°C to 27° C (73°F to 81°F) that is soft (50-100mg/L) and acidic (pH 6.0).[2] The fish is reported to be peaceful and social.[2]
Aquarists recommend that it be fed prepared foods and small live foods.[2]
Breeding is difficult, as parents must be prevented from eating their own eggs. Eggs usually hatch within 20–24 hours.
The H. pulcher does best in groups of 6 or more.
