Breastspot Cleanerfish

Interesting Info

• The Breastspot Cleanerfish, is a tropical wrasse found throughout the Indo-Pacific, including the Great Barrier Reef, Coral Sea, Papua New Guinea, Solomon Islands, Vanuatu, and parts of Indonesia.
• Its most distinctive feature is the large oval black spot on its breast, located just behind the pectoral fins — a unique marking that sets it apart from other cleaner wrasses.
• The body is pale yellow to whitish with a bold black stripe running from the snout through the eye and along the upper body, narrowing toward the tail.
• Males and females are similar in appearance, though males may display brighter colours and more pronounced breast spots during breeding periods.
• Juveniles resemble adults but often have a proportionally larger and darker breast spot, making them especially distinctive.
• Like other cleaner wrasses, they establish cleaning stations where larger reef fish visit to have external parasites, mucus, and dead tissue removed.
• Clients include reef sharks, trevallies, parrotfish, surgeonfish, and groupers, many of which allow the tiny cleanerfish to enter their gills and mouths unharmed.
• Their cleaning services are so vital that many predatory fish avoid eating them, recognising their role in reef health.
• They occasionally “cheat” by nipping mucus from client fish rather than parasites, which can cause the client to flinch or swim away.
• Breastspot Cleanerfish are protogynous hermaphrodites — all individuals start as females, and the largest in a group can transform into a dominant male.
• Spawning occurs in pairs or small groups, usually in the late afternoon, with eggs released into the water column to drift as plankton until hatching.
• Their lifespan is estimated at 4–6 years, though this depends heavily on reef health and the abundance of client species.
• The species name pectoralis refers to the prominent black spot located near the pectoral fins, the key identifying feature of this cleanerfish.
