Scientific name: Glossolepsis incisus
The Red Rainbowfish reaches a length of six inches and does best in groups. This deep-bodied species requires a large tank with both swimming space and planted areas. This fish should be kept at a water temperature of 72º to 76º Fahrenheit, with a pH between 7.0 and 7.5 and moderately hard water. Although it will accept flake and freeze-dried foods, live foods such as brine shrimp or blackworms should also be provided.
The Red Rainbowfish hails from Papua New Guinea. Females are a soft, pale golden color, while the males are a fiery red. As with the Dwarf Rainbowfish, males show a bright yellow blaze on the forehead during courting.
