he One Spot Foxface is a hardy, peaceful herbivore known for its striking yellow body and single black spot near the tail. Reaching up to 8 inches, it requires a spacious tank (at least 75 gallons) with plenty of swimming space and live rock for grazing. It feeds primarily on algae but will also accept a variety of herbivore-based prepared foods. While generally reef-safe, it may nip at soft corals or LPS if underfed. Caution is advised when handling, as its dorsal spines are venomous. It’s a great algae controller and typically peaceful, though it may be shy at first.
