Chelmon rostratus
Animalia›Chordata›Actinopterygii›Perciformes›Chaetodontidae
📍 Indo-Pacific
Stunning butterfly with orange-copper vertical bands and a long beak for probing crevices. Popular for eating Aiptasia pest anemones in reef tanks. Notoriously difficult to acclimate — refuses dry food and needs live or frozen worms.
