Origin

Asia; Lake kutubu rainbowfish is found in the upper Southern Highlands of New Guinea.

Sexing

When the males are mature they will have deeper bodies than the females and display brighter coloration.

Breeding

Spawning mops or plants should be added to the breeding tank. The parents will spawn easily if conditioned on meaty foods. Once they have spawned remove the parents and feed the fry on Infusoria or egg yolk initially. When they start to grow, they can be fed on crushed algal flake or newly hatched brine shrimp.

Lifespan

The expected life span for Melanotaenia lacustris is 5-8 years.

Short description

Melanotaenia lacustris are classed as a peaceful species but some adult males may prove to be fin nippers. They should be kept in small groups with a well planted tank. Open swimming spaces should also be allowed for.
