The glass anemones are often introduced to an aquarium along with rocks or water. They are livebearers that can quickly colonize a tank, to the detriment of other Anthozoa. However, they do have advantages in an aquarium with butterfly fish (Chaetodontid family), as they constitute these fishes' staple diet. Diameter: 5-10 cm.
