The Bi-Color Foxface, scientifically known as Siganus uspi, is a stunning and eye-catching fish species that belongs to the Siganidae family. This marine beauty is admired for its unique coloration and striking appearance, making it a popular choice among aquarium enthusiasts.
Originating from the Indo-Pacific region, particularly found in the coral reefs of the Indian Ocean and the Pacific Ocean, the Bi-Color Foxface showcases a captivating combination of vibrant yellow and deep brown or black hues. Its body is laterally compressed and oval-shaped, with a distinctive elongated snout and large, protruding eyes.
This species is relatively larger in size compared to other rabbitfish, reaching an average length of around 8-12 inches (20-30 cm) when fully grown. Its body is predominantly yellow, with bold brown or black markings on its face, dorsal fin, and tail. The contrasting colors create a striking bi-color pattern that adds to its visual appeal.
The Bi-Color Foxface is known for its peaceful temperament and active swimming behavior, gracefully gliding through the water column. It requires ample swimming space and a well-established reef or marine aquarium with plenty of hiding spots and live rock formations to mimic its natural habitat.
When it comes to feeding, the Bi-Color Foxface is primarily herbivorous, feeding on various types of algae and seaweed in the wild. In a home aquarium, it should be provided with a varied diet consisting of high-quality marine-based foods, such as algae sheets, spirulina flakes, and other herbivore pellets or flakes. Supplementing their diet with fresh vegetables, like blanched spinach or seaweed, can also be beneficial for their overall health and well-being.
Providing optimal water conditions is crucial for the well-being of the Bi-Color Foxface. They prefer a well-maintained aquarium with stable water parameters, including a temperature range of 72-78°F (22-26°C) and a pH level of 8.1-8.4. Regular water changes and the use of a good filtration system are essential to maintain water quality.
While the Bi-Color Foxface is generally peaceful, it may exhibit territorial behavior towards similar-looking species or other rabbitfish. It is recommended to introduce them to the aquarium as the last addition to minimize aggression. Keeping only one Bi-Color Foxface per aquarium is usually advised, unless you have a very large tank with ample swimming and territorial space.
Overall, the Bi-Color Foxface is a captivating and highly desirable addition to any reef or marine aquarium. Its unique coloration, striking appearance, and peaceful nature make it a standout species that adds beauty and elegance to your underwater world. With proper care, a suitable environment, and a well-balanced diet, the Bi-Color Foxface can thrive and become a stunning centerpiece in your aquatic display.
The Bicolor foxface can camouflage it's skin when distressed or at night time while sleeping to hide from predators. Typically the bicolor will take on a cow like pattern, but will return to its normal self quickly.
Caution - The Foxface's dorsal spines are venomous which deters his predators. Although peaceful, he will flare his dorsal fin when startled or threatened and you should be mindful of this while feeding or when placing corals/settings rocks. As long as you are aware of the Foxface's location within your tank, and you don't suddenly place your hand near him, there is limited chance for direct contact. Be cautious while hand feeding.
