Description & Biology

Although they are commonly smaller fish, they can get up to 9 in (22.9 cm) in length, and are grey in color with a blue iridescent, metallic like finish. [4] The younger fish have a yellow dorsal fin with blue tips on it while the older ones on the other hand get more dull in color as they get older. [4] This species feeds on plankton including copepods. [5] This species has high haplotype diversities. [3]

Distribution & Habitat

Chromis ovalis is endemic to the Hawaiian Islands and tends to live near remote islands. [4] They can be found as schools in rocky areas as deep as 20 feet. [6]

Reproduction

The males of this species create nests which are around 3 feet apart in short term nesting areas. [6] In order for the males to get a mate, similar to a mating dance, the male jumps to gain the females attention, if the female is interested then she follows the male to the nesting area to lay her eggs. [6]
