Gold-rim Chromis

📖 Overview

This species was observed at Yap (Caroline Islands), in a group of about a dozen individuals living among large (about 1-2 m) rock boulders just above the upper edge of a precipitous drop-off. A juvenile of approximately 4 cm SL was observed at a depth of 120 m, below the site where the type specimens were collected. Its color pattern was consistent with that of the adults . Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding . Eggs are demersal and adhere to the substrate . Males guard and aerate the eggs .
