Red Rainbowfish

Red Rainbowfish, commonly known as Glossolepis incisus, make a bold freshwater display with their reflective scales and deep bodies. Mature males develop the characteristic red coloration; females and juveniles usually look more subdued. Color varies with maturity and individual condition.

Aquarium & care

Plan for adults reaching approximately 15 cm. We recommend a 75-gallon aquarium or larger with at least 4 feet of swimming length for an adult group. Provide plants along the sides and back, open water through the center, and gentle circulation with reliable filtration. Suitable conditions are 72–77°F (22–25°C), pH 7.0–8.0, and approximately 10–20 dGH. Maintain stable water and regular partial water changes.

Feeding

Offer complete tropical flakes or pellets and varied, appropriately sized frozen foods. Feed measured portions rather than allowing food to accumulate.

Temperament & tankmates

Keep at least 6–8 together. They are generally peaceful but their size and activity can unsettle smaller, slow-moving fish. Select robust community companions with matching water requirements.
