Holopristis pulcher has a pale-lemon background color with a black area on the flanks, up to the caudal peduncle.[2] Under subdued lighting, H. pulcher's body appears iridescent.[2] It grows up to 4cm (1.6in).[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 to 27°C (73 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.
