Anemonefish, or “clownfish”, are certain species of fish that live inside of anemones. Unlike all other fish, they are protected from the stings of the anemone’s tentacles.

Sometimes, the anemone gets parasites that the anemonefish can pick off, and the anemonefish chases away fish that like to eat anemones. How would you classify their symbiosis?
