These opportunistic anemones can be identified by their resemblance to miniature palm trees, with a polyp body and an oral disc bordered by tentacles. There are many different species of Aiptasia; some varieties are transparent, while others are mostly light brown or tan in color, ranging in size from a few centimeters to a few inches. The brown color of most Aiptasia found in aquariums is due to a symbiotic relationship with zooxanthellae, tiny plant cells living within the Aiptasia's tissue that provide the anemone with much of its nutrients and energy.
Like all members of the Cnidaria phylum, Aiptasia have the ability to sting for both offensive and defensive purposes; the tentacles near the oral disc have stinging cells called nematocysts that can sting fish, crustaceans, corals, and live rock in your aquarium. As an added defensive mechanism, Aiptasia can also withdraw into tiny holes in your live rock if threatened.
