Hitchhiker Nudibranch

[eTrain]

I recently restarted my 27g cube. I got 4lbs of live rock to help seed and the first interesting thing so far has been this dime sized grey/translucent nudibranch. Since the only other inhabitants are 4 hermits I didn't see the immediate need to remove it. Hopefully that isn't the wrong decision. From everything I've read nudibranchs diets are very specific so there is already a food supply or it will slowly starve. Kinda sad but that is somewhat the nature of the hobby. I couldn't get a good picture of it but I have a macro lens on the way which will hopefully help. Has anyone had good experiences with them? Almost everything I've found was a coral eating horror story.

Most nudibranchs aren't reef safe. If it were my tank, I'd probably just remove it (and freeze it).
