The Crimson Spotted Rainbow comes from the eastern coastal drainage systems of northern New South Wales and southern Queensland, Australia. They are a subtropical species found in relatively still, clear water, in water temperatures between 11-34°C. Habitat includes freshwater rivers, streams, billabongs, reservoirs, swamps, and lagoons with dense aquatic vegetation. Their natural environment is subjected to seasonal variations with water temperature, pH and hardness levels varying considerably.
The Crimson Spotted Rainbow are omnivores and are opportunistic feeders in the wild, with a natural diet of small crustaceans, insects, and some vegetation. In captivity, they should be given a high quality diet to encourage good colouration. A mix of live and processed foods is necessary for optimal health.
The Crimson Spotted Rainbows do fine in a larger fish community aquarium of similarly sized fish, but do exceptionally well in a geographical tank stocked with other rainbows. Although generally non-aggressive, overly aggressive or very shy tank mates will make bullies out of them. Mix them with other playful but good natured fish for best results. You may notice some chasing between rainbows, but this is rarely a concern unless a fish is injured, has nowhere to hide, or is constantly harassed (usually a result of one of the first two).
Crimson Spotted Rainbows are schooling fish and the ratio of males to females is very important to keep a reasonable peace among them. Although you can always keep single sex schools, you will see significantly better colouration if both genders are in the tank.
