🐠 One Spot Foxface (Siganus unimaculatus)
A Bright Yellow Body With a White, Black-Striped Head • A Single Dark Spot Unique to Every Individual • An Excellent Natural Algae Grazer
 
📋 The One Spot Foxface, also known as the Blotched Foxface, is a striking fish, with a bright yellow body, a white head marked with a black stripe over the eye and chest, and a single distinctive dark spot toward the tail that gives the species its name. This spot varies between individuals, ranging from an almost perfect circle to a free-form blotch, meaning no two fish look quite alike.
It comes from coral reefs and rocky lagoons across the Indo-Pacific, an excellent natural algae grazer, closely related to and often confused with the more common Foxface Lo. Every One Spot Foxface we ship is feeding well.
Like all rabbitfish, this species carries venomous dorsal and anal spines that it flexes when threatened, comparable in severity to a bee sting rather than anything more serious, though care is still needed during handling, and any puncture should be treated with appropriate caution. This turns out to be a real advantage in the tank: predatory or assertive tankmates tend to leave it entirely alone once they respect those spines. One quirk worth knowing: this species can rapidly shift to a mottled, muted brown-grey colouration when stressed, sleeping, or startled, this is completely natural and not a sign of illness, provided it's still eating and behaving normally. It reaches up to 20cm, so a 265L tank suits it well.
