Bold and territorial, king angelfish patrol the boulder slopes in pairs, their electric-white tail fins flashing against dark basalt. They feed on sponges, tunicates, and algae, playing a key role in keeping encrusting growth in check on the reef structure. Juveniles display vivid orange vertical stripes and are commonly seen in shallower rock crevices at 5 to 10 m.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
