This colour form of the Doublayi rainbow has been most popular in the aquarium hobby. It has the most intense colours of all the Doublai colour morphs. The scales are almost all metallic blue, as show in the close-up view of their scales above.
These fish come from South East Queensland and can tolerate much lower temperatures that the far northern species of rainbows. In their natural habitat the water temperatures during winter can be as low as 15C in some of the smaller water holes.
Pictured right is one of the water holes in Kangaroo Creek where our brood fish were collected. Kangaroo Creek is in South East Queensland. It is a very small creek system that has suffered as a result of the drought. It is unusual these days to see much water flow through this area. The creek is usually a series of water holes which were flushed regularly during the wet season.
