no kidding i just browsed through 200 different genus of nudibranch and sea slugs lol and thats still the closest i can come up with.although when i look further into it i doubt it is because its only food is a striped anemone and i dont think they are found in the hobby but i could be wrong.most nudis feed on certain things and dont stray from that diet so whatever you have unless the rock is n ew is feeding somehow and its more than likey on algae or coral
