You won't find it for sale that way. Most of the Indonesian octopuses from Live Aquaria (not Diver's Den) are aculeatus (but they have shipped others and don't ID the species). Often animals labeled as "Bali" octopuses (from other vendors and from wholesalers) are aculeatus. About the only vendors that come close are the collectors in the Keys who acquire them from the fishermen and they miss ID on occassion.
