 Examples of facultative cleaners are commonly wrasse species such as the blue headed wrasse, noronha wrasse ("Thalassoma noronhanum") and goldsinny wrasse ("Ctenolabrus rupestris"), sharp nose sea perch in Californian waters, and the lumpfish ("Cyclopterus lumpus").Using the example of the blue wrasse from Caribbean waters, their alternative feeding strategy is described as being a generalist forager, meaning they eat a wide variety of smaller aquatic organisms based on availability.When displaying cleaning behaviour, it has been noted that the blue wrasse inspects potential clients and only feeds on some, implying that the wrasse is seeking out a particular type of parasite as a diet supplement.
