🐠 Foxface Rabbitfish (Siganus vulpinus)
A Vivid Yellow Body With a Black-and-White Fox Mask • An Outstanding Natural Algae Grazer • Venomous Defensive Spines That Deter Tankmates
 
📋 The Foxface Rabbitfish, also known as the Foxface Lo or Common Foxface, is one of the most instantly recognisable marine fish, with a vivid yellow body and a distinctive black-and-white "fox mask" pattern across the face, exactly where the common name comes from.
It comes from coral-rich lagoons and reef slopes across the Western Pacific, including the Philippines, Indonesia, and the Great Barrier Reef, an outstanding algae grazer, widely valued for controlling nuisance hair algae, bryopsis, and bubble algae in reef tanks. Every Foxface Rabbitfish we ship is feeding well.
Like all rabbitfish, this species carries venomous dorsal and anal spines, similar in severity to a lionfish sting, which it raises defensively when threatened, exactly why even more assertive tankmates tend to leave it alone. Care is needed during handling and tank maintenance to avoid accidental contact. One quirk worth knowing: this species can rapidly change to a mottled, camouflaged colour pattern when stressed or sleeping, this is completely natural and not a sign of illness. It's reef safe with caution; a well-fed specimen generally leaves corals alone, but if underfed it may nip at soft coral polyps. It reaches up to 23cm, so a 265L tank suits it well.
