Dear Andy,
Your photo is instantly recognisable as Durvilledoris lemniscata. Sorry I didn't have a clue from the sketch you sent earlier(and I didn't post on the Forum). I guess you got this in your aquarium from some 'live rock' you bought, which was presumably from somewhere in the Indian or Pacific oceans. Concerning its food. It is a member of the nudibranch family Chromodorididae, which feed exclusively on sponges, each species having its particular preferences. Unfortunately we don't know the food preference of most species, and that includes this species. Probably there was a small colony of its preferred sponge on your live rock or it is in a severe state of starvation. Your chance of finding a colony of the right sponge by luck are probably zero.
Best wishes,
Bill Rudman
