Comments: Special handling is required to yield survival rate to day 4. Gentle circulation used to keep larvae in suspension. Larvae 2.8 mm at first feeding. Need an acceptable food. 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 loriculus appearsto be a combination of lori, (Malayan), a parrot, and -cul, =a, =um, =us (Latin), little. The Lori is a brilliant red parrot and again a word root (-culus) indicates something small.

The common name is “Flame Angel” which is attributed to the brilliant red color.
