The White-Face Butterflyfish (Chaetodon mesoleucos) is a striking reef fish native to the Red Sea. It features a silver-gray body, contrasting black bands, and its signature pale white face that gives the species its name. This butterflyfish moves gracefully through rockwork and corals, often seen in mated pairs or small groups in the wild.
While hardy once acclimated, it can be challenging to adapt to aquarium life due to its specialized feeding habits. Its beauty and calm demeanor make it a favorite among experienced marine aquarists and public exhibits that can meet its dietary needs.
Provide a mature aquarium (75 gallons or larger) with plenty of live rock for grazing and hiding spaces. They prefer stable reef-like conditions with strong water quality, moderate lighting, and calm tankmates.
Because of its coral-eating tendencies, this species is not suitable for reef aquariums containing live corals. Keep singly or as a bonded pair; avoid aggressive or fast-feeding tankmates that may outcompete it for food.
In captivity, feeding can be a challenge. Offer:
Feed small amounts 2–3 times daily, especially during acclimation. Encourage feeding by introducing live foods if necessary.
