Australian Rainbowfish

Australian Rainbowfish are omnivores that thrive on high-quality flake foods and small pellets as staples, supplemented 2-3 times weekly with frozen foods like brine shrimp, daphnia, or bloodworms. Include vegetable matter such as blanched spinach or spirulina-based foods to support their natural diet of small crustaceans and plant material. Feed small amounts once daily, only what they can consume in 2-3 minutes.

These active, schooling fish are highly social and display vibrant iridescent coloration when kept in groups of 6 or more, becoming dull and stressed in smaller numbers. They are peaceful community fish that spend most of their time in the mid-water column, constantly moving and exploring. Males may display mild territorial behavior toward each other, but aggression is minimal compared to other rainbowfish species.

Breeding in captivity is moderately difficult and requires patience; they are egg scatterers that rarely breed in standard aquariums without specific conditioning. Successful breeding requires slightly cooler temperatures (around 24°C), dense vegetation or spawning mops, and well-conditioned pairs fed high-protein foods. Fry are tiny and require infusoria or liquid fry food for the first week before accepting microworms or newly hatched brine shrimp.
