These were photographed by Raphaël Forns in about 1m of water on an Ailuk Atoll lagoon pinnacle. I wouldn't have hesitated in calling them P. modestus but those are supposed to live in Pocillopora coral species. However, the Stylophora coral these were in are in the family Pocilloporidae, so I suspect P. modestus will be correct.
