Longfin Bannerfish

Heniochus acuminatus


These were abundant on the reef, and I assumed they were juvenile Moorish Idols.

Thanks for the correction!

Ah, this isn't a moorish idol, but a bannerfish! It's a really common mistake, they look freakishly similar but aren't that related at all. This is in fact a kind of butterfly fish! There are two types, and judging from the longer snout, I'm going with longfish bannerfish (also called a pennant coralfish).
