Bicolor Foxface Rabbitfish

Bicolor Foxface Rabbitfish (Siganus uspi) is a peaceful species that is completely reef-safe, making it an excellent choice for mixed reef systems as it poses no threat to corals or invertebrates while focusing primarily on algae grazing. This striking rabbitfish displays a dramatic color split with the front half of the body in bright yellow and the rear half in deep black or dark brown, creating a bold two-toned appearance complemented by the characteristic fox-like face and constantly grazing mouth used for tireless algae consumption. The vivid bicolor pattern and diligent algae-eating behavior make it both a stunning visual centerpiece and highly functional reef cleaner. It can reach about 8-9 inches in adult size. Best kept in tanks of at least 100 gallons or more due to their active swimming and grazing nature, with abundant live rock for natural algae growth, stable water parameters, and caution around their venomous dorsal spines which require careful handling, though they're generally very peaceful and often become quite personable with their owners. Its diet should focus heavily on marine algae—nori sheets, spirulina, dried seaweed, quality herbivore pellets—with occasional meaty supplements like mysis shrimp, as this primarily herbivorous species requires constant access to plant matter for proper health and will effectively control nuisance algae while maintaining their spectacular bicolor appearance.
