Entacmaea quadricolor (Bubble-tip anemone)


The Bubble-tip anemone appear in a variety of colors:  rose, orange, red, and green.
Its tentacles has bulbous tips.


Has not yet been assessed for the IUCN Red List.


Widespread throughout the tropical waters of the Indo-Pacific area and the Red Sea.
Large adult specimens, with tentacles that are more streaming or stringy, are often found in deeper waters with more dimly lit conditions. These specimens are often solitary, while smaller, younger specimens are often located in groups or colonies nearer to the surface, in bright sunlight. These specimens tend to show the characteristic bulbous tips on their tentacles.


Can multiply by sexual and asexual means. One way is using fission, which is when they actually split in half from the foot or mouth to form a clone.
Or the Bubble-Tip Anemone will brood juvenile anemones for a few days within the oral cavity before releasing them into the water. When released, the embryos float and then connect and start out as a fully formed anemone, or may be able to travel some distance without feeding.


This anemone can grow to be up to 30 centimetres.

Prey / Predation

It obtains the majority of its energy from solar radiation.
Nutrients are generally obtained by filter feeding using its sweeping tentacles, or through wastes and debris cleaned from the surface of its partner anemonefish.

Special features

It maintains a symbiotic relationship with the anemonefish, which can be “hosted” by the anemone by providing it with defence against predators and also providing some nourishment. In turn, the anemone provides the anemonefish with shelter.
