A trumpetfish pauses for a quick hygiene appointment, courtesy of a yellow nose goby. A voracious predator, the trumpetfish has no interest in making a snack of the goby, one of several species of cleaner fish in the Caribbean. In a classic example of mutualism, both species benefit from this arrangement. The trumpetfish gets rid of some annoying parasites, while the goby gets a free and easy meal.
