Community Living

An anemonefish community is unlikely any land-animal group; none of the fish found in the one anemone are related and therefore, anemonefish do not live in family groups. This type of community is common in reef fish though.

So how do the fish get in the anemone without being related? Its one of those amazing reef occurences; when young anemonefish hatch from their eggs at the base of the anemone (they are called fry), they float away on currents. In the currents they eat and swim. Somehow they have a built in homing device which allows them to swim back to the same area of their birthplace and locate a host anemone that is friendly to their species. Just how they do it, is still a mystery.
