Minyichthys is a circumtropical genus of pipefishes consisting of species from the Indo-Pacific and eastern and western Atlantic regions. The genus is characterized as having a maximum standard length of about 60 mm, with two or three anal fin rays. Minyichthys species can be differentiated from members of the closely related genus Micrognathus by their higher frequency of total subdorsal rings (seven to 11 as opposed to three to seven).
