Here's a pair of Bandit Angelfish. These are the only "large" angelfish you'll likely see in the main Hawiian Islands, as most of our angelfish are dwarf species. They reach up to about 7 inches and are typically found only at depths of 60 feet and below in Kona. I've heard they're found shallower more frequently over on Kauai. They're endemic to the Hawaiian Islands as far as I know, you won't find them anywhere else.
We're always happy to see these guys.
