Australia; Black banded rainbowfish is found in the eastern part of Australia where it inhabits the waterways and is sometimes found in the brackish estuaries.
Males tend to be larger and more colourful than the females; the females will also lack the dark edging on the fins.
Add a spawning medium to the tank, java moss or an artificial spawning mop is ideal, and then proceed to do some large regular water changes to trigger spawning. The female will lay up to 50 eggs per day; once spawning is complete move the eggs to another tank. Depending on the temperature, the eggs should hatch in one week and the fry, when free swimming, can be fed on Infusoria initially. As they grow, feed them on newly hatched brine shrimp.
The expected life span for Melanotaenia nigrans is 3-5 years.
Melanotaenia nigrans need to be kept in groups of at least 6 specimens. They do best in a planted tank, but provide open swimming areas for them.
