this is a stretch but maybe you could call the folks at the SC aquarium.... its been awhile since ive been, i dont remember what type of octo they were supposed to have packed in that small tank with ten flounders but who knows, maybe they can give you a lead on a source....
I have heard that Tampa Bay Saltwater (TBS), which cutivates live rock off the Florida coast and in the Keys, might be able to supply you with a briareus.
