Origin

Australia; Slender rainbowfish are to be found only on the northern tip of Western Australia.

Sexing

Very easy fish to sex; the male has red margins on the dorsal and anal fins.

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 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 gracilis is 5-8 years.

Short description

Melanotaenia gracilis are a relatively rare species in the aquarium hobby, especially outside of Australia. Hiding places and shelters are a must in the tank; floating plants will also put these fish at ease. The water should be neutral to slightly acidic.
