Etymology: Centropyge: Greek, kentron = sting + Greek, pyge = tail (Ref. 45335). More on authors: Randall & Yasuda.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 1 - 56 m (Ref. 1602), usually - m (Ref. ). Tropical; 0°C - ; 28°N - 15°N
Western Pacific: known only from the Mariana and Ogasawara Islands; possibly a population southwest of Palau.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 9710); common length : 7.0 cm SL male/unsexed; (Ref. 37816)
soft rays: 17 - 18. Its ground color is variable, ranging from almost red to light apricot. The barring can be reduced to a small patch behind the operculum, and in rare cases, be entirely absent. The blue trim on the soft dorsal and anal fins is absent or reduced in females and highly developed in males.
A common species (Ref. 9710) found singly or in small groups in exposed outer reef slopes and occasionally in clear lagoon reefs. Prefers areas of mixed dead and living corals with numerous shelter holes and passages (Ref. 1602). Feeds mainly on benthic algae. Forms harems of 3-7 individuals. Occasionally exported through the aquarium trade (Ref. 48391).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03311 (0.01551 - 0.07068), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
