Food and feeding
As with all rainbow fish these are omnivorous, they will accept all quality flakes and pellets. Treat them with blood worm and brine shrimp once per week.
Asia/Oceania; Goldie river rainbowfish are found in the river systems of New Guinea.
Mature males will display much brighter colors than the females. Their first dorsal fin will also overlap the second, with females there is no overlapping.
Add java moss or spawning mops to the breeding tank. Slightly alkaline water is much preferred, and when ready the females will scatter their eggs around the moss or mops. Once the eggs have all been laid, remove the parents and cover the tank over to emit most of the light. The eggs should hatch after one week and the free swimming fry should be fed on Infusoria initially, as they grow newly hatched brine shrimp can be offered.
The expected life span of Goldie river rainbowfish is 5-8 years.
Melanotaenia goldiei are a very peaceful species of fish but they are also very active. Open swimming spaces are required in the tank and they must be kept in small groups.
