Notes

Crimson-spotted Rainbow Fish are bony fish. They have three stages in their life cycle: egg - juvenile - adult.

Crimson-spotted Rainbow Fish have silvery, blue-grey sides with a shining yellow colour. They have a red spot behind their eye on their gill cover. Males often have red spotting on their fins.

Crimson-spotted Rainbow Fish live east of the Great Dividing Range between southern Queensland and northern New South Wales . They are often found in streams, rivers, dams and ponds.

Crimson-spotted Rainbow Fish eat insects, tadpoles, plants and worms.

Larger fish, giant water bugs and water spiders, turtles and water rats all like to eat Crimson-spotted Rainbow Fish.
Crimson-spotted Rainbow Fish breathe by using their gills to absorb oxygen from the water. Water enters through the fish's gills and flows past a rich blood supply. The oxygen passes from the water through the thin gill membranes into the fish's blood.

When Crimson-spotted Rainbow Fish breed, each female will lay several eggs a day in the breeding season. Eggs are then fertilised by the male. Sticky threads help the eggs stick to plants in the water. About one week later the eggs hatch.

Crimson-spotted Rainbow Fish help control mosquitoes because they eat mosquito larvae which live in the water.
