The typical reef tank is a community in which a mixture of all sorts of invertebrates and fish are kept. Although these can be beautiful, there are other ways to build a coral reef aquarium, and there are animals that need a special aquarium. This includes the pizza anemone (Cryptodendrum adhaesivum) and its interesting symbionts.

Pizza anemones are one of the sea anemones that serve as hosts for clownfish from the genera Amphiprion and Premnas. However, only one species of clownfish, Amphiprion clarkia, has been observed to live in association with this anemone. The anemone is the host and the fish live "in association with” or "in mutualism with” it — both parties benefit from the fact that they live together. The fish move some distance away from the host, but they are still associated with the anemone.
