Sparisoma chrysopterum (common names: redtail parrotfish, blue parrotfish, kwab, pink kwab, pink parrot, blisterside, and blue black-finned chub) is a species of parrotfish.

Description The upper end of the pectoral fin base shows black saddle-shaped markings while they are young adults. Commonly, there is a light, saddle-shaped area on top of caudal peduncle. The dorsal, pelvic, and anal fins are orange or red in colour. Juvenile specimens or those in the initial phase have a mottled pattern similar to the substratum. This provides camouflage when they rest on the sea floor.

Distribution This species lives in the western Atlantic Ocean from Brazil in the south, north to Florida and the Bahamas. It also occurs throughout the Caribbean Sea.

Diet Sparisoma chrysopterum This species grazes on seagrasses and algae growing in the benthic zone.

Parasites This species is known to host an ectoparasite in the genus Caligus named Caligus atromaculatus (C.B. Wilson, 1913).
