The Foxface Rabbitfish is a striking saltwater species that brings personality and vibrant color to any marine aquarium. Its bold yellow body and unique black and white facial markings make it a favorite among hobbyists. At Squeaky’s Aquatics, our Foxface Rabbitfish are available exclusively for in-store pickup and are cared for with the highest standards and health monitoring.
Species Overview
The Foxface Rabbitfish (Siganus vulpinus) is well known for its hardy nature, peaceful temperament, and impressive algae-eating abilities. This fish can reach up to 8–9 inches in length, making it ideal for medium to large aquariums. Its gentle disposition allows it to thrive with a variety of peaceful tankmates, and its appetite for algae helps keep tanks clean and healthy.
Aquarium Requirements
Foxface Rabbitfish require a mature marine aquarium with ample swimming space and live rock for grazing. A minimum tank size of 75 gallons is recommended to ensure enough room for natural behaviors and growth. Stable water conditions are crucial: temperature should be maintained between 72–78°F, pH between 8.1–8.4, and specific gravity from 1.020–1.025. Regular water testing and maintenance are essential to keep this species healthy.
Feeding & Diet
This species is primarily herbivorous. Foxface Rabbitfish thrive on a diet rich in marine algae, nori, and high-quality herbivore pellets and flakes. Providing a variety of greens helps prevent them from sampling soft corals or polyps. Supplementing their diet with occasional fresh vegetables and seaweed sheets encourages natural grazing behavior and supports vibrant coloration.
Compatibility & Behavior
Foxface Rabbitfish are peaceful and do well with other non-aggressive marine fish. They can coexist with tangs, clownfish, gobies, and similar species. Avoid keeping them with highly aggressive fish or other rabbitfish to prevent territorial disputes. Foxfaces are generally reef safe but may nibble on soft corals if not properly fed, so attentive feeding is recommended for reef tanks.
Handling & Safety
The dorsal spines of the Foxface Rabbitfish are venomous and should be handled with care. Always use a net or container when moving the fish and avoid direct contact with the spines. While not aggressive, their natural defense mechanism can cause a painful sting if mishandled.
