Asia; Irian jaya rainbowfish are endemic to Lake Sentani, Indonesia.
Males have a reddish body colouration with reddish fins. Females will have clear fins with a yellowy brown colouration.
Add java moss or fine leaved plants to the breeding tank. Add one pair to the tank and raise the temperature slightly. Spawning will last over a few weeks with several eggs being laid per day. Once spawning is complete, remove the parents to prevent them from eating the eggs, when the fry are free swimming they can be fed on Infusoria initially.
The expected life span for Melanotaenia irianjaya is 7 years.
Always keep this rainbow fish with other peaceful species and provide open swimming spaces at the front of the tank but add planted areas towards the rear. A tight fitting lid is required as these fish are great jumpers.
