Magnificent Foxface (Siganus magnificus)

The Magnificent Foxface is a spectacular marine aquarium fish, prized for its bold black, white, yellow and reddish markings. Also known as the Magnificent Rabbitfish or Red Fin Foxface, this eye-catching species makes a stunning centrepiece for a spacious marine aquarium. Its distinctive facial mask and contrasting body colours make it a particularly desirable choice for marine fish enthusiasts.

Magnificent Foxface Care Requirements

Native to the eastern Indian Ocean, the Magnificent Foxface inhabits coral reefs and rocky environments where it grazes on naturally growing algae. In captivity, it needs a mature marine aquarium with excellent water quality, plenty of live rock and generous open swimming space.

An aquarium of at least 500 litres is recommended for a single adult, with larger tanks preferred for long-term care. Provide caves and sheltered areas where the fish can retreat when startled.

Maintain a stable temperature of approximately 24–28°C, salinity of 1.023–1.025 specific gravity and a pH of 8.1–8.4.

Feeding Your Magnificent Foxface

This rabbitfish primarily feeds on algae and other plant material. Offer a varied diet of nori seaweed, marine algae, spirulina-based foods and quality herbivore pellets. Small amounts of suitable frozen marine foods can also provide variety.

Regular feeding and access to natural algae help maintain its health and reduce the likelihood of unwanted coral nipping.

Compatibility and Reef Suitability

The Magnificent Foxface is generally peaceful with compatible marine fish and can be kept in reef aquariums with caution. Although many specimens coexist successfully with corals, individual fish may nip at soft corals, large-polyp stony corals or other fleshy polyps. Monitor its behaviour after introduction.

Like other rabbitfish, it has venomous fin spines that can deliver a painful sting. Take particular care during aquarium maintenance, capture and transport.

Add a Magnificent Foxface to Your Aquarium

With its exceptional colouration, active swimming behaviour and natural algae-grazing habits, the Magnificent Foxface is an impressive addition to a suitable established marine aquarium. Provide plenty of swimming room, a balanced algae-rich diet and consistent water conditions to help this remarkable species thrive.
