Blue and brown chromis formed loose aggregations over the reef, retreating toward th
reef benthic microhabitats when approached by predators, or when the current was
strong. The creole wrasse (Clepticus parrae) is another zooplanktivorous fish that wa
observed swimming in streaming schools over the reef, foraging larger reef spaces th
the chromis species. Bicolor damselfish (Stegastes partitus) and fairy basslet (Gramma
loreto) are demersal and territorial fishes that were present in all transects surveyed at
30 m. These are both carnivores that feed mostly upon reef zooplankton (Randall,
1967). The bridled goby (Coryphopterus glaucofraenum) was typically associated with
