Hey folks,

I recently added a new starfish to my tank and it looks like he may have claimed my spotted goby.

Aside from keeping him well fed - anyone know much about the green sea stars? I think that's what it is. He's a starfish but a very active one who can navigate the length of my tank in under a minute.

I'm not sure how to safeguard the rest of my critters if he's going to go on a rampage from time to time.
