Cowrie eats Pocillopora, etc. ID?

[cdalmost]

Hi all, I recently obtained this cowrie with some live rock, and it turns out it eats sponges and Pocillopora, and maybe more. It is currently living in my refugium, where it seems to be eating the soft pinnate hair algae. Anyone know the identity and what I can do with it?

On a related note, which cowries are safe for the reef aquarium?

 

[cdalmost]

Oh, and this particular cowrie did eat end up eating all of the Bryopsis algae in my refugium, but hasn't touched any of the macro algae or the green star polyps.

Actually, it has been munching on the greens star polyps. I guess it's not all bad...
