As mentioned previously (Behavior), A. ocellaris is part of a symbiotic relationship between three species of sea anemones, Heteractis magnifica, Stichodactyla gigantean, and Stichodactyla mertensii (Myers 1999). In this relationship, the fish receives protection from the anemone in the form of daily shelter and for its nest. The anemone receives protection too, as it has been documented that in the absence of a guest fish, the anemones may be attacked by butterfly fish or even turtles (MarineBio 1998). Additionally, in the presence of the fish, bulbs are found on the end of tentacles that are believed to increase surface area available to solar energy (Fautin and Allen 1992). The bulbs are not present in the absence of the fish. (Fautin and Allen, 1992; MarineBio, 1998; Myers, 1999)
