Bicolor Foxface

The Bicolor Foxface, *Siganus uspi*, is a striking and unique rabbitfish species known for its distinctive coloration. Its anterior half is typically a vibrant yellow, transitioning sharply to a dark brown or black posterior, including the caudal fin. This bold, two-toned pattern makes it a captivating addition to a marine aquarium.

A minimum tank size of 125 gallons is recommended for the Bicolor Foxface due to its potential size and active swimming habits. They are generally peaceful towards tankmates but can be territorial towards other rabbitfish or similarly shaped fish. They are known for their herbivorous diet and are excellent algae grazers, making them beneficial for controlling nuisance algae in the aquarium.

In the aquarium, the Bicolor Foxface will readily accept a varied diet of high-quality marine flake food, pellet food, and various forms of marine algae, such as nori. Offering a diverse diet is crucial for their health and vibrant coloration. They typically reach a maximum size of around 8 inches in captivity. Like other rabbitfish, they possess venomous spines in their dorsal, anal, and pelvic fins, which should be handled with caution. They are considered to have an intermediate care level, requiring stable water parameters and a suitable environment.
