Word origin: Centr, -I, -o (Greek). The center; a point, spur. pygm, (Greek) dwarf. The common name “Pygmy” or Dwarf” angel is apparent from the word root pygm. Centro may be in reference to the spine (spur) at the angle (The center) of the preopercle. The genus argi has two possible word roots; arg, -o (Greek) shining, bright, or argi, =a (Greek) Idleness, leisure. Since this species is not brilliantly colored (nor silvery) the latter word root would seem more appropriate and may be a reference to activity. Additionally roots listed with an possible ending preceeded by an equal ( = ) sign may be used alone.
The common name is Cherubfish or Dwarf Angelfish
