Jenny, these nuds are really not good for anyone's tank unless you are trying to have an all stoney coral tank. They will eat all zoathids and cloves and gloves. The only reason I'm asking if anyone would like them is b/c I've heard there maybe someone trying to create an all stoney tank. Once they have rid all their small softy polyps these nuds will die off.
Most nuds are not reef safe, but in a fish only with live rock tank you could probably keep one, but like mentioned, they need a constant supply of food and don't tend to live very long in a home aquaria. This can get very expensive as I'm fairly sure they feed on only live foods like sponges, byrozoans and tunicates. Oh, these guys are toxic too! If you want one wait a year or two once your tank as fully matured and in the meantime do lots of research on them. I think the colorful ones are very beautiful, but I really don't trust myself (whether I'm experience enough or even able) to keep them happy and alive. Good luck and happy researching
