Australian Rainbowfish (Melanotaenia fluviatilis) School

The Banded Rainbowfish was described by Rendahl in 1922. However, this fish was actually first collected by a Norway zoologist in 1895, from the St. Mary river. This rainbow fish comes from northern Australian continent. Their distribution is across discontinuous waters across northern Australia. They have extremely limited areas where they can be found and these are Melville Island, Mary River, Arnhem Land, and Groote Eylandt. The common names of this fish describe both its appearance and its origins. These include Jewel Rainbowfish, Regal Rainbowfish, Three Stripe Rainbowfish, and the Goyder River Rainbowfish. The Banded Rainbowfish is not listed on the IUCN red list.Due to the changes in their natural environment these Goyder River Rainbowfish can live in many different conditions. They typically inhabiting well vegetated streams and waterholes, presumably congregating in schools like other rainbow fishes. They can be found in creeks and streams with clear moving water to swamps, lagoons, and even stagnant puddles during the dry season. The substrate of their nature habitat is usually made up of rocks and small stones covered in dead leaves. This fish is normally found under cover of floating plants or submerged bog type wood. They are omnivores that feed on aquatic insects, plant material and algae, and small amounts of terrestrial insects.

Australia; Australian rainbowfish are to be found in New South Wales and Queensland.

A 30 gallon aquarium is minimum, but these are moderately large and very active swimmers, so a tank size of 50 - 60 gallons or more is advisable. Additionally, the tank should be securely covered as these fish are skilled jumpers and will probably do so if given the opportunity. Rainbow fish will do best and are most effectively displayed in tanks which simulate their natural habitat. A sandy substrate, dense vegetation, and bog wood all echo the native rivers of the Australian Rainbowfish. Try, if possible, to plan for one or two hours of sunlight hitting the tank. This should be at a time when you can view the tank as the illumination will make the fish even more stunning.As with most of the Rainbowfish species they are most at home in well planted aquariums. When you choose plants make sure to pick plant that can tolerate the hard, alkaline conditions preferred my this fish. They also need stretches of open swimming areas. An efficient filter and good water movement are needed for the male fishes to develop their coloration.

Female Australian Rainbowfish are a more drab version of the males.

- Breeding and raising the Australian Rainbow fish, Pseudomugil gertrudae and Pseudomugil signifer. Australian Rainbowfish do best in an aquarium that simulates their natural habitat. A densely planted tank with a sandy substrate, some and plenty of swimming space is all that is needed to keep these fish health and happy. If possible, place the tank where it can get a couple hours of sunlight during the day. They prefer hard alkaline water but will thrive in a wide range of conditions, as long as the water is well filtered and moderate water movement is provided.

Although Australian Rainbowfish do well in a community tank with other active, peaceful, similarly sized fish; they are especially suited for a single species tank with other rainbowfish of the same species. They do best in groups of at least 6 to 10 individuals that are equally male to female. Although they are generally non aggressive, they are extremely active and playful and can bully some slower swimming species. House them with other active, playful, non aggressive species for the best outcome.
