Common name: Longnose Butterflyfish

Oxymonacanthus is a genus of fish in the family Monacanthidae, known for species like the Longnose Butterflyfish. These fish are admired for their elongated snouts and vibrant patterns. In the wild, they are often found in pairs and are obligate coral feeders, primarily consuming Acropora polyps. In captivity, they require a diet that mimics their natural coral-based feeding habits, which can be challenging to provide. They are best suited for experienced aquarists who can cater to their specialized dietary and environmental needs.
