Blue Chromis
Blue Chromis
Description:
Body laterally flattened, oval in profile, with a slender, deeply forked tail with dark borders. Body brilliant blue, with dark on the nape, along the back and on the borders of the tail. No black spot at the base of the pectoral fin. Dorsal fin ending in a sharp point.
Ecology
Common above deep outer reefs, usually at 3 to 5m, but can be found down to 25m or more. It maintains territories on the reef face, but often swims in the water column above the reef to feed on plankton. It is often seen alone or in small groups, and it tends to stay close to the reef. Juveniles are found close to the bottom to escape predators.
Life Cycle:
The males of this species are solitary spawners that have a solitary breeding territory. They spawn with numerous females and guard the eggs until the planktonic larvae hatch (after approximately three days).
