Do Nudis only eat Zoa's?

Does a nudibranch's diet only consist of Zoanthids? For example, if a tank was Zoa-less for an X amount of time, would all Zoa-eating Nudibranches eventually starve to death?

Thats exactly how I got rid of mine after 3 failed dipping attempts. I set up a bare quarantine tank and moved all my zoos to it and kept them there for over 6 months. I did dips every two weeks for about two months to the quarantined zoos to kill the nudis but still kept them out of the main tank for several more months to make sure any nudis and hatching eggs in the main tank would starve to death.

I believe most nudis are specialized feeders (there is more than one type btw). If it eats one thing in the wild it will probably not change diet in the aquarium.
