Glossolepis pseudoincisa Allen & Cross 1980

The Millennium Rainbowfish are active and will definitely liven up the aquarium. Being a schooling species it is best to keep a group of 20 of the adult with a good ratio of males and females. The males will display their most brilliant colors brightly popping out while posturing each other.

Glossolepis pseudoincisa will do best in aquariums that simulate their natural habitat. The tank should have sandy substrate and vegetation best planted in the sides and back, living a stretch of open water in the middle. Rockwork could be a beautiful additions to the Lake Ifanten rainbowfish tank.

In its natural environment this species tends to congregate in groups around the margins of lake covered with dense vegetation. Lower temperatures, close to 21° C, will encourage males to display brighter colors.

Adult males develop much higher back than females. The coloration of the males is bright red, while the females are greenish-yellow.

Glossolepis pseudoincisa is an omnivore species. In its natural biotope it feeds on small crustaceans, insect larvae, algae and detritus. As aquarium they will accept up to 70% flake or pellet food. Other 30% should be made up of a variety of live foods: bloodworms, tubifex worms, brine shrimp, and daphnia.

Glossolepis pseudoincisa is an egg scatterer. Separate a well fed breeding pair and introduce them to the spawning tank. The breeding aquarium should have slightly hard, alkaline water with a pH 7.5 and a temperature 26 °C. This species lay their eggs on fine-leaved plants such as java moss. A small raise in temperature can induce spawning.

High quality diet of frozen and live foods: Artemia sp., Mysis sp., microworms.

Males will display intensive red that  depends upon age, health, temperature, water quality, mood, and even rank in the school. A brilliant neon orange strip serves as a breeding signal to females. Females and young males are silvery brown.

Usually the healthy pair will spawn for a period of several weeks, laying a few eggs each day. These are attached to java moss or spawning mop by a small thread.

The male will display an amazing show of intense colors on the spawning site by doing a “headstand” over the produced by female eggs. After the spawning the pair will rest. The spawning mop or plants should be removed ot replaced otherwise the eggs will be eaten. The fish will repeat this daily with steadily decreasing numbers of eggs produced. The parents should be removed when egg numbers fall or when the females show signs of fatigue.

For the growth of the young it is necessary to administer an infusoria–type food for the first few days, until they are large enough to shrimp nauplii, microworm and other micronized food.

Although the adults tend not to eat the spawn, it’s easier to raise the fry in a separate aquarium. It is recommended to checking the plants daily and remove the laid eggs to a raising tank with the water from the spawning tank.
