 An example of an obligate cleaner is the shark nose goby ("Elacatinus evelynae") in the Caribbean Reef, where it has been observed to perform up to 110 cleanings per day.Cleaning stations are a strategy used by some cleaner fish where clients congregate and perform specific movements to attract the attention of the cleaner fish.Cleaning stations are usually associated with unique topological features, such as those seen in coral reefs and allow a space where cleaners have no risk of predation from larger predatory fishes, due to the mutual benefit from the cleaners' service.
