Distinguishing features

A silver fish with a low, inconspicuous dorsal fin. Usually seen in in pairs along the edges of reefs and in passes. Interior of mouth and tongue are white but this is not a good field character.

This species was in LIFG up to Aug 2023, based only on a photo taken and identified by Andy Lewis from an unknown location. AH thinks the photo is of Craterognatus plagiotaenia.
