Tube anenomes are a great way to add some vibrancy to your reef tank. Just be sure to give them a sandy substrate to live in. You will also want to give them space because they can sting any other corals near by.
Tube anenomes are also non-photosynthetic, so you don't have to worry about how much light they are receiving. Just be sure to feed them 1-2 times a week.
