The Japanese Rubyfish occurs throughout the Indo-west Pacific region.  It is known from a few localities in northern Western Australia and Queensland.

The species is an emmelichthyid fish (family Emmelichthyidae). The bonnetmouths (also known as the red baitfishes, redbait and ruby fishes) are represented by two genera and five species in Australian waters.

They are mostly bottom-dwelling fishes that occur at depths between 100 m and 400 m. The primary food item is zooplankton.
