In the cleanerfish–client mutualism involving the Indo-Pacific cleaner wrasse Labroides dimidiatus and its reef fish clients, mechanisms such as ‘tactile stimulation’, partner switching and punishment are used by clients to control cheating by cleaners.

Indirect effects of mutualisms may have important implications for surrounding ecosystems through changes in density, species composition, or behavior; however, the latter has been difficult to quantify....
