It is a small species rarely exceeding {{convert|38|mm}} standard length.[1] It feeds on zooplankton, particularly ostracods and copepods.[2][3] Sexual maturation occurs at length of about 22 mm, and adult males have more developed olfactory organs than females, i.e. the species is sexually dimorphic.[4] References1. ^{{Cite journal| volume = 142| pages = 1–128| last = Baird| first = R.
