Several species of sea anemones are available to aquarium hobbyists, but the bubble-tip anemone (Entacmaea quadricolor) is certainly the most popular, and for good reasons.The Bulb Anemone is one of the most beautiful ornamental anemones for the home reef. Color: Entacmaea quadricolor occurs in tan, orange, brown, rarely found red, pink, maroon and common green colors. When housed beneath intense aquarium lighting, Entacmaea quadricolor develops a unique bulb tip at the end of its tentacles. When hungry, this member of the Actiniidae family will stretch its sweeper tentacles to grab food from the water column. After feeding, the tentacles then shorten again and take on their bulbous appearance. Red variations may be referred to as Rose Anemones. Generally, Bulb Anemones from Fiji and Tonga are shaded in soft browns, tans, or maroon, though an occasional green specimen is found. By contrast, the Bulb Anemones from Singapore are typically green in color with a deep maroon base. The Bulb or Bubble Tip Anemone is found in oceans around the world. The Bulb Anemone attaches its pedal disc deep within dead coral amongst rubble or on solid, living reefs. In the home aquarium, the Bulb Anemone requires similar habitat and positioned amongst deeply creviced live rock or branchy corals placed in sandy substrate. Most Bulb Anemones prefer to find their own place to settle and may move about your aquarium until a suitable location is found.
