There are a variety of anemones that can host clownfish, but the best anemone for hosting clownfish is the Entacmaea quadricolor. This anemone is also known as the Bulb-Tipped Anemone or Bubble Tip Anemone. It is native to reefs in the Indo-Pacific region and has a distinctive bulbous tip on each of its tentacles. The Bulb-Tipped Anemone is one of the most popular anemones among aquarists because it is relatively easy to care for and its Tentacles are not as poisonous as those of other anemones.
