Metallic Foxface (Siganus vulpinus “Metallic”)
The Metallic Foxface is a striking and peaceful herbivorous marine fish, known for its shimmering metallic green-gold body contrasted by vivid black markings and a bright yellow tail. Its unique coloration and graceful swimming behavior make it a captivating centerpiece in reef aquariums. Despite its bold appearance, it is generally calm and adds both beauty and utility by grazing on nuisance algae.
Size: Typically grows up to 9 inches in length
Country of Origin: Indo-Pacific region, including the Philippines, Indonesia, and northern Australia
Latin Name: Siganus vulpinus
Care Level: Moderate – thrives in well-established aquariums with stable water parameters, ample swimming space, and plenty of algae or supplemental herbivore foods
Metallic Foxfaces are herbivores that feed primarily on marine algae. In captivity, their diet can be supplemented with dried seaweed, spirulina, and herbivore-specific pellets or flakes. They are reef safe, though care should be taken around small invertebrates, and their venomous dorsal spines should be handled with caution. Their elegant appearance and algae-grazing habits make them a highly desirable addition to both reef and fish-only marine systems.
