Olele waters, as one of the leading diving location for tourism in the Gorontalo Province, lack information about its resources. The reef fish diversity, which is a major tourist attraction, has never been evaluated. This research was conducted to determine the structure of reef fish communities in Olele waters. The survey was carried out using a visual census method in two zones: away from the settlement and close to the settlement. A total of 26,466 individual reef fishes were found during the study, with a density of 8.82 ind m-2. The Pomacentridae family has the highest number of species among all stations. Shannon diversity (H'), Shannon similarity (E), and Simpson dominance (C) index indicate that the Olele waters belong to a biodiversity category characterized by a high diversity, stable community conditions, and a low dominance. © 2020, BIOFLUX SRL.
