Heniochus acuminatus (Linnaeus, 1758)
Longfin bannerfish

This is an uncommon species at Kwajalein most often on lagoon bottom shipwrecks at depths of 30 to 45m. Occasionally specimens are observed around lagoon reefs, usually on the slope at depths greater than 20m or so, and a very few specimens have been observed on the seaward reef. We usually see them in pairs, but have occasionally observed groups of up to about five individuals. It feeds primarily on plankton.
