What type of symbiotic relationship does the moray eel and cleaner fish?

The relationship between moray eels and cleaner fish is a type of mutualism. In this symbiotic interaction, cleaner fish, such as cleaner wrasses, remove parasites and dead skin from the moray eel's body, providing the eel with hygiene benefits. In return, the cleaner fish gain a food source and protection while feeding on the moray's skin. This relationship enhances the health of the moray eel while ensuring the cleaner fish have access to sustenance.
