Not much as many eat coral and elyssia is one that eats algae and others from the sacoglossan group

Not really. Most nudibranchs are thought to be carnivorous and to have way too specific of dietary needs to keep them in our tanks effectively. I'm not aware of any that eat a wide variety of sponges, and - unfortunately - most sponges tend to be pretty difficult to keep in our tanks anyway.

That said, there are a few different Sacoglossan slug species (mostly Elysia spp. - A.K.A. lettuce nudibranchs - though you can sometimes find Oxynoe spp. for sale too) available in the hobby that are reef safe, safe to keep with lettuce nudibranchs, and would eat algae.

The 2 nudibranchs you have pics of there are Hypselodoris apolegma and a Phyllidia sp., probably Phyllidia varicosa. They both eat highly specific sponge species, and would be basically impossible to keep at this point.
