New Guinea Rainbow
First described by Weber in 1908, the Glossolepis incisus is best known in the aquarium hobby as the Red New Guinea Rainbow. This is a peaceful, schooling fish that can reach up to 6 inches in length. Males will develop the characteristic deep red coloration at about 2 inches in size and the color will intensify as the fish matures. The male will also develop a more pronounced humped back, almost giving the head a “beak-like” look. They can tolerate harder/alkaline water and are large enough to hold their own with other larger fish. The New Guinea Rainbow is a carnivore in the wild, so will require meaty based foods in the aquarium. The adults are rather easy to get to spawn, but the fry would require rotifer cultures to raise. The fry is a very slow growing species.
