This branching, long tentacle anemone is part of a marine coral reef aquarium, where it is fixed to live rock. Saltwater fish tanks with living reefs require excellent filtration systems to ensure a good water quality and also a gentle water flow. Strong lighting, as well as specialist food and minerals, are also a requirement, while the marine fish must be chosen carefully so that they don't eat the coral.
