Cetoscarus pulchellus (Rüppell, 1835)
Cetoscarus bicolor, the bicolour parrotfish, is a species of fish belonging to the family Scaridae.
It is monotypic within the genus Cetoscarus, although the scientific name C. bicolor has been suggested to be reserved for the population in the Red Sea, in which case the remaining populations are named C. ocellatus.
It is among the largest parrotfishes, growing to a length of up to 90 cm (35 in). As in many of its relatives, it is a sequential hermaphrodite, starting as female (known as the initial phase) and then changing to male (the terminal phase). The initial phase is dark brown with a large cream patch on the upper part of the body. The terminal phase is very colourful, overall green with pink spotting to the body and edging to the fins. Juveniles are white with a black spot on the dorsal fin and an orange band through the eye.
Bicolour parrotfish is associated with coral reefs. It usually can be found in lagoon and seaward reefs at depths between 1 and 30 m.
