Distribution: Australia; distribution across the northern parts of Australia
Main Ecosystem: River; clear flowing water
Temperament: Peaceful; and schooling
Diet: Ominvore; Accepts all flake and granular foods for use with tropical fish, especially fond of bloodworm, blackworm, and glassworm. Overfeeding of bloodworm, and exclusive live feedings without the vitamin balance of artificial foods however , tends to cause ill health in this species, including darkening colour associated with hepatic lipidosis, and general obesity. A balanced approach to feeding must be taken.
Care: While tolerating average water values, this fish is susceptible to high nitrates and will suffer repeated fungal infection particularly on the mouth and lips if water changes are not regularly performed. While these infections are rarely serious , and can be easily treated, it is better to prevent them with clean water. Should be kept in schools of at least two males to several females to show their best colors and activity. This fish can get to 15 cm in length, and 6 cm in body depth. With this size, and the need to be in schools, it is recommended they are kept in a large tank with plenty of open swimming area. 55 gals being the recommended minimum size.

They are very prolific, and will breed readily in most water parameters. The problem lies in the raising of the fry. The fry are very small, and grow slowly. They require large amounts of very small foods, and very clean water. Start the fry off with infusoria or vinegar eels. The parents will eat the eggs, and subsequent fry, so a separate fry tank will be needed fo
Comments: One of the most beautiful of all the Rainbows. This fish is also one of the more confusing of all the Rainbows, as it comes from many different places in the country. It sports a variety of color differences from these different areas as well, with the Goyder River being one of the brightest reds of all. This fish is often confused with the Crimson Spot Rainbow.
