Cleaner fish are small fish that help maintain the health of larger fish by eating parasites, dead skin, and other debris from their bodies. They typically set up "cleaning stations" where larger fish come to be cleaned. This mutualistic relationship benefits both parties: the cleaner fish get food, while the larger fish enjoy improved health. Common species of cleaner fish include the cleaner wrasse and goby. These fish are often brightly colored, which helps attract larger fish. The cleaning process is usually gentle, and the larger fish often display relaxed behaviors, indicating their trust in the cleaner fish.
