Morphology | Morphometrics
(total): 14 - 18;
soft rays: 15 - 20. Male blackish on fins and anterior three-fourths of body , and yellow caudal-fin with median black band. Female yellowish with 3 broad, greyish double bars divided by thin grey line, broad black bar at base of caudal-fin, and greyish head with brown markings. Head, chest, and pectoral-fin base scaleless; long and slender orbital tentacle; mandibular pores 3-4 + 3-4 + 3-4. Maximum size to 3.2 cm TL (Ref. 90102).
Adults are found in coral and rocky reefs (Ref. 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). Feeds on small benthic invertebrates (Ref. 89972).
