Description

Scientific Name: Siganus uspi

Common Names: Bicolor Foxface, Uspi Rabbitfish, Uspi Foxface, Uspi Spinefoot

Maximum Length: 12 inches (30 cm)

Minimum Aquarium Size: 100 gallons (380 liters)

Aquarium Suitability: The Bicolor Foxface is best suited for larger aquariums due to its potential size and active nature. Ideal for reef and fish-only tanks, it thrives in peaceful, well-maintained setups. This species should be housed with other non-aggressive fish to minimize territorial disputes. It is a great addition to aquariums with plenty of space to swim and explore.

Foods & Feeding: The Bicolor Foxface is herbivorous, primarily feeding on algae and plant matter. In captivity, provide a diet rich in algae-based foods such as nori, spirulina, and algae wafers. You can supplement their diet with occasional vegetables like lettuce or spinach, along with meaty foods like shrimp or mysis to ensure balanced nutrition. A varied diet is essential for their long-term health.

Reef Compatibility: Siganus uspi is generally reef-safe, as it does not harm corals or invertebrates. However, its herbivorous diet may cause it to graze on certain types of soft corals or macroalgae, so it’s important to monitor its behavior in reef setups. It can help control algae growth, making it a beneficial addition to a well-maintained reef tank.

Captive Care: The Bicolor Foxface is relatively hardy but requires a well-established tank with stable water conditions. A tank with plenty of live rock and hiding spaces is recommended to reduce stress and provide the fish with grazing opportunities. While peaceful, it can become territorial, especially with other rabbitfish, so it’s best to house it with other peaceful species in a large tank.

This vibrant, algae-eating fish is a fantastic addition to larger aquariums, offering both beauty and utility with its active swimming habits and natural ability to help control algae.
