That's what I what was afraid of, I think I will just pass on getting one.I've never heard of that being done successfully. A lot of clubs will have a lettuce nudibranch that gets passed around for algae problems. I want to get one because I have a bryopsis issue at the moment, but yet to see one at the LFS that I can trade back in for credit once my algae issue is gone. You can find plenty of stories of people getting them, running out of algae, then trying to find something it will eat without success.
