Fox Face Rabbit Fish Siganus Vulpinus

The Foxface Rabbitfish is a hardy and attractive reef fish known for its bright yellow body, contrasting white face, and bold black eye band resembling a “fox mask.” Peaceful, active, and excellent at controlling nuisance algae, it’s both a practical and striking addition to larger reef or community aquariums.

Native to the Western Pacific, including Indonesia, the Philippines, and the Great Barrier Reef, Siganus vulpinus inhabits coral reefs and lagoons, typically found in pairs grazing on algae-covered rocks.

An herbivorous grazer that thrives on a diet of marine algae, seaweed, and plant-based foods. Provide spirulina, nori, and high-quality herbivore pellets, along with occasional meaty foods for variety. Feed 2–3 times daily for best color and vitality.

Peaceful and reef-safe with caution. It coexists well with tangs, wrasses, angelfish, and other community fish, but may occasionally nip soft corals if underfed. Avoid aggressive or predatory species.

Generally peaceful, though mild territorial behavior may occur toward similar-shaped fish. Provide plenty of swimming space and live rock for grazing and security.

Excellent for intermediate aquarists. Hardy, adaptable, and highly beneficial for algae control, the Foxface Rabbitfish thrives in well-established aquariums with stable water conditions.
