Bulb Anemone
Entacmea quadricolour
The Bulb Anemone is often referred to as the Four-colored, Bulb Tentacle, Bulb Tip, or Bubble Tip Anemone. Red variations may be referred to as Rose Anemones. The appearance of the Bulb Anemone can vary greatly from one individual to the next. Under intense lighting, the tentacles will develop bulbs at the tips.
The Bubble tip anemone is usually found in coral rubble, or in solid reefs. Its pedal disc is usually attached deep within dead coral. It stretches its tentacles to become sweeper tentacles when hungry. That is, the tentacles become elongated to capture a meal, then the tentacles shorten and the bubble tips return.
Handle this invertebrate, and all Anemones, with care. They can sting other Anemones, as well as Corals.
The Bubble tip anemone needs strong illumination with live rock full of deep holes and crevices, or branchy corals placed in the sand. They require an aquarium of at least 120 litres, as they can grow up to 30cm across in the aquarium. These anemones will typically remain compact and will gain bulb tips under intense lighting. If the lighting is insufficient, they will expand their bodies to great lengths to make the most of the available light. It should be kept with a Clownfish for best results. At times, the tentacles may appear stringy; this may be due to insufficient light or the need for food.
Its diet should include chopped fish, shrimp, or worms if a clownfish is not present.
The Small bubble tip anemones from Fiji and Tonga are typically colored in shades of brown, tan or maroon with an occasional green specimen.
Due to variations within each species, your aquatic life may not look identical to the image provided.
