Eastern Rainbowfish

Eastern 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 with vegetable matter such as blanched spinach or spirulina-based foods to support coloration and overall health.

These are active, schooling fish that spend most of their time in the mid-water column, constantly swimming and foraging. They are peaceful and social, displaying best colors and behavior when kept in groups of at least 6 individuals where they establish a loose hierarchy. Males may display mild fin-flaring to each other, but aggression is minimal and rarely causes injury.

Breeding in captivity is moderately difficult and requires patience, as these fish are egg-scatterers with no parental care. Condition breeding pairs with live foods, provide fine-leaved plants or spawning mops, and maintain water temperatures around 26-27°C with slightly acidic to neutral pH. Expect 100-300 eggs per spawn; remove parents immediately after spawning to prevent egg predation, and fry will free-swim in 7-10 days.
