What Is This?!?

That's a SW sea dragon, related to sea horses and pipe fish. Last I knew, they were not available for sale commercially, due to endangered status. I've seen them in some larger public aquariums from time to time.
 
Ah the Shedd--excellent place, though I have to put it second to the Monteray Bay Aquarium. That place is outa control!
 
Oliver may have them on his site because he does import a lot of stuff for aquariums in the general geographic area. One of the best sources for any kind of wild fish, especially discus, absolutely best source of wilds.
