The bubble-tip anemone (Entacmaea quadricolor), also known as the bubble tip anemone, bubble anemone or bulb anemone, is a species of sea anemone of Indo-Pacific origin. In the wild, this anemone is a natural host of several species of anemonefishes, including the Cinnamon (Amphiprion melanopus), Tomato (A. frenatus), Orange-fin (A. chrysopterus) and Maroon (Premnas biaculeatus).

E. Quadricolor anemones often appear in a variety of colormorphs including, rose, orange, red and standard green. This sea anemone can grow to be up to a 30 cm (1 ft) in diameter, and obtains the majority of its energy from solar radiation (sunlight) via its symbiotic zooxanthllae. Nutrients are generally obtained by filter feeding using its sweeping tentacles, or through wastes and debris cleaned from the surface of its partner clownfish. Nevertheless, it has been witnessed that the clownfish will feed their host anemone. In aquariums, this sea anemeon will reproduce asexually when in proper care with supplemented minerals such as iodine and other trace elements (usually purchased as an enrichment cocktail by most home aquarists).
