Morphology | Morphometrics
A facultative cleaner. Observed to feed on periphyton and to clean parasites from Lethrinops cf. lituris. Additionally it has been observed to clean parasites from Cyrtocara cf. fenestrata and C. cf. picta. The host fish approaches P. pursus and positions itself with its dorsal fin oriented toward the cleaner, and permits P. pursus to remove ectoparasites from its fins and scales.
