Eastern Central Pacific: endemic to Hawaii, but its use as a baitfish may spread its range.

Biology     Glossary (e.g. epibenthic)

Epipelagic (Ref. 58302). A schooling species living close inshore and entering bays, inlets, estuaries, canals and even penetrating into fish ponds, thus able to tolerate a wide range of salinities. Feeds mainly on planktonic crustacean larvae. Breeds throughout the year, with a peak in summer, spawning at night (between 2200 and 0200 hours) in bays and estuaries (Ref. 189).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Spawns in bays and estuaries. Spawning is said to be continuous throughout the season (Ref. 32412, 40290).
