Masked Rabbitfish

Masked Rabbitfish (Siganus puellus) 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 distinctive rabbitfish displays a pale yellow to cream body with a striking black mask extending from the mouth through the eyes and across the forehead, creating a dramatic facial pattern reminiscent of a bandit's mask, complemented by the characteristic rabbit-like mouth used for constant algae consumption. The bold black facial masking against the light body color and tireless grazing behavior make it both a uniquely attractive addition and highly functional reef maintenance crew member. It can reach about 9-10 inches in adult size. Best kept in tanks of at least 125 gallons or more due to their active swimming and foraging nature, with abundant live rock for natural algae growth, stable water parameters, and careful handling around their venomous dorsal spines, 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 distinctive masked appearance.
