New Golden Wonder Killifish - Surface-Dwelling Predator • Brilliant Gold Color • Hardy & Active

The Golden Wonder Killifish (Aplocheilus lineatus) is a striking surface-dwelling freshwater fish known for its brilliant metallic gold coloration, elongated body, and bold personality. This “gold” morph of the Striped Panchax is a longtime favorite for aquarists looking to add color and activity to the top level of the aquarium.

Golden Wonder Killifish are hardy and adaptable, making them suitable for intermediate community tanks with appropriately sized tankmates. They are natural surface hunters and help control insects and small pests, while their constant cruising behavior adds dynamic movement to the aquarium.

Best kept in well-covered tanks (they are excellent jumpers), Golden Wonders thrive in planted aquariums with open swimming space and stable water parameters.
