Lettuce nudibranch

Anyone have experience with the lettuce nudibranch?

Yes they seem to only eat bryopsis, and relatively little at that. They like light and hang out in view sunning themselves which is cool to see. But they do not last long in any reef tank environment. I've only been able to keep them long term in a tank that uses sponge filters for filtration. They will be killed eventually by most any other pump or filter. Nem guards do not work they can fit through the smallest of holes.
