Turquoise Rainbowfish

Turquoise rainbowfish are omnivores that thrive on a varied diet of high-quality flake foods, small pellets, and regular offerings of frozen foods like brine shrimp, daphnia, and bloodworms. Feed small amounts once daily, providing only what they can consume in 2-3 minutes. Supplement occasionally with vegetable matter such as blanched spinach or spirulina-based foods to support coloration and overall health.

These are highly active, peaceful schooling fish that should always be kept in groups of at least 6 individuals to reduce stress and encourage natural shoaling behavior. They occupy the mid to upper water column, constantly moving and displaying their brilliant turquoise coloration, especially when in good condition and around feeding time. Males may display mild fin-flaring to establish hierarchy, but aggression is minimal and directed toward their own species only during breeding season.

Breeding in captivity is possible but requires patience and specific conditions including slightly acidic to neutral water (pH 6.5-7.0), temperatures around 24-26°C, and dense vegetation or spawning mops where eggs can be deposited. Females are prolific egg-layers, scattering eggs among plants; parents do not guard eggs and will consume them if given the opportunity. Fry are tiny and require infusoria or liquid fry food for the first week before accepting newly hatched brine shrimp.
