There are two kinds of longnose butterflyfish in Hawaii, the common longnose and the big longnose. Neither name is especially flattering, but I think this is a big longnose butterflyfish. It feeds mostly on small shrimp, which it catches by thrusting its long nose into small crevices and swallowing its prey whole.
The little bright-eye damselfish on the left might have been startled by the butterflyfish, but not threatened. They can be quite aggressive in defending their small territories.
You post such gorgeous photos. Thank you!!
