The Fiji Foxface (Siganus uspi), also known as the bicolor rabbitfish, is a visually interesting member of the rabbitfish family native to the coral reefs of the South Pacific, particularly around Fiji. This fish is admired for its hardy nature and utility in saltwater aquariums, where it can help control algae growth.

Distinguishing Features of the Fiji Foxface

• Appearance: The Fiji foxface has a body coloration that is generally grayish or light brown with a contrasting dark, almost black, upper body. This dark area often has a soft-edged, blotchy appearance and extends over the upper portion of the body, giving it a two-toned look. It also has a distinctive facial mask pattern around the eyes, similar to the look of other foxface species but with a subtler color palette.

• Size: It can reach up to about 10 inches (25 cm) in length, making it a moderate-sized fish that needs ample space to swim.

• Habitat: Native to coral-rich reefs, especially around Fiji, this fish prefers environments with plenty of rock structures and algae to graze on.

• Diet: An herbivore, the Fiji foxface primarily feeds on algae in the wild. In captivity, it helps control algae in aquariums and should be provided with seaweed-based food, like nori, along with other plant-based supplements to maintain its health.

• Behavior and Compatibility: Generally peaceful, the Fiji foxface can cohabit well with a variety of tank mates. However, it may display mild territorial behavior towards other rabbitfish species. It is typically reef-safe, but if it lacks sufficient algae, it may occasionally nip at soft corals.

• Venom: Like other rabbitfish, the Fiji foxface has venomous spines on its dorsal, anal, and pelvic fins. Though not deadly to humans, its venom can cause a painful sting, so it's important to use caution when working around it in the tank.
