The millennium rainbow (Glossolepis Pseudoincisus) is a medium sized fish native to lakes in West Papua New Guinea (formerly Irian Jaya) in Indonesia. This fish grows to an adult size of about 4 inches long. Adult males develop a brilliant red coloration, while females are brownish to olive green in color.
The millennium rainbow should be maintained in an aquarium of 30 gallons or larger. A dark colored soft, sandy substrate (CS6631) is a good choice. Driftwood (ZM2000) and live or artificial plants may also be incorporated.
The millennium rainbow prefers a temperature of 70°F to 89°F, a pH of 6.5 to 8.5, and a hardness of of up to 15 to 25°H.
The millennium rainbow is an active, high energy fish. Good tank mates include other species of rainbows, larger tetras, barbs. cory catfish, and many loricariid catfish. It is a shoaling species that should be kept in groups of at least 6, but more is always better.
In the wild, the millennium rainbow is an omnivore feeding on small aquatic crustaceans, worms, insect larvae and algae. In the aquarium it will readily accept most prepared foods. Good choices include flakes (AL165) and frozen bloodworms (SF4792) or brine shrimp (SF6777). For maximum color, growth, and health these fish will look their best when given probiotics (AL169) in addition to a balanced diet.
