Rainbow Shiners appreciate clean, well-oxygenated water with good filtration and moderate water movement. A varied diet consisting of quality prepared foods supplemented with frozen or live foods can help encourage excellent growth, condition, and vibrant coloration.

Each fish is carefully selected, health-checked, and professionally packed to help ensure it arrives healthy and ready to acclimate to its new aquarium.

Please Note: Coloration varies depending on sex, age, breeding condition, diet, and environment. Mature males typically develop the most intense rainbow coloration, particularly when in breeding condition.
