Phoenix Islands Protected Area (PIPA) in the Republic of Kiribati is one of the largest marine protected areas in the world (408,250 km[superscript 2]). These reefs are extremely remote (Fig. 1a) and, therefore, escape many anthropogenic impacts. While snorkelling in the shallow lagoon at Kanton Island (2°47′25″S 171°42′48″W) in September 2015, we came upon unusually high cover (∼100 %) of tabular Acropora (A. hyacinthus and/or A. cytherea) (Fig. 1b) and strikingly high numbers of Chaetodon trifascialis. Up to 25 individuals were observed coexisting within a relatively small area of ∼4 m[superscript 2] (Fig. 1c). Moreover, there were additional individuals present under the coral colonies out of view. Based on size, all individuals within the group were adults or sub-adult and clearly displayed overlapping ranges with minimal conspecific aggression.
