Whiteface Butterflyfish (Chaetodon mesoleucos)

The Whiteface Butterflyfish is a striking and rare species known for its unique coloration and graceful demeanor. Native to the Indian Ocean, this beautiful fish is a favorite among aquarists seeking an elegant centerpiece for their fish-only or fish-only with live rock (FOWLR) setups. Its bold markings and active swimming make it a captivating addition to any marine aquarium.

Appearance: The Whiteface Butterflyfish features a distinctive black and white coloration. Its body is primarily white, with bold black bands running diagonally across its sides, creating a stunning contrast. The fish's head is accented by its namesake "white face," which is framed by a black mask running through its eyes. Its fins are edged in yellow, adding a subtle but beautiful splash of color to its elegant appearance.

Behavior: The Whiteface Butterflyfish is an active and curious swimmer that enjoys exploring open spaces and rock formations in the tank. It is generally peaceful but may exhibit mild territorial behavior, especially in smaller aquariums. When properly acclimated, this butterflyfish becomes a confident and engaging presence, constantly moving and adding dynamic energy to the aquarium.

Diet: In the wild, Whiteface Butterflyfish feed on coral polyps, algae, and small invertebrates. In captivity, they require a varied diet that includes high-quality marine flakes, pellets, and frozen foods such as mysis shrimp and brine shrimp. Offering sponge-based foods and algae-rich diets is essential to replicate their natural feeding habits and maintain their health and vibrant coloration. Frequent, small feedings throughout the day are recommended to keep them well-nourished.

Tank Requirements: The Whiteface Butterflyfish requires a minimum tank size of 75 gallons to accommodate its active swimming and need for space. The tank should include plenty of live rock for grazing and hiding spots. Stable water parameters and excellent filtration are crucial for their well-being, as they can be sensitive to poor water quality.

Tankmates: Whiteface Butterflyfish are generally peaceful and can coexist with other non-aggressive species such as tangs, wrasses, and gobies. However, caution should be taken when housing them with other butterflyfish or similarly shaped fish, as they may become territorial. Providing ample space and plenty of hiding spots helps minimize potential conflicts.

Reef Aquarium Compatibility: The Whiteface Butterflyfish is not considered reef-safe due to its tendency to nip at corals, particularly soft and stony corals, and some invertebrates. They are best suited for fish-only or FOWLR aquariums, where their beauty can be fully appreciated without risking damage to delicate reef organisms.

Max Size: The Whiteface Butterflyfish can grow up to 6 inches (15 cm) in length, making it a medium-sized butterflyfish that requires a well-structured and spacious aquarium.

Origin: This species is native to the Indian Ocean, particularly around the Red Sea and waters near East Africa. It is commonly found in coral-rich areas of lagoons and reef slopes.
