Comments: Generally found on sloping, low profile bottoms with branching hard and soft corals (predominantly <i>Sarcophyton</i> and <i>Xenia</i>) at about 20 m. Observed to be in large mixed aggregations with <i>P. paineorum</i> and <i>P. flavianalis</i>. Also, a number of suspected hybrids (most likely <i>P. alfiani x P. paineorum</i>), with the colors of this species and the filamentous rays of <i>P. paineorum</i>, were also observed in the area.
