📖 Overview

The area of collection (type locality) has a flat, low profile bottom at the base of a gentle (approximately 30°) slope at 34 m depth; substrate consisted of a dense mixture of spindly, branched Seriatopora hystrix coral (Pocilloporidae) and Halimeda alga. Numerous groups of this species were observed, each containing about 1-3 males and up to about 20 females. Courtship activities were common with males continuously 'flashing' a short distance above the bottom .
