As I mentioned in a prior post, the Indonesian octos from Live Aquaria journaled on TONMO have always turned out to be either abdopus or macropus complex animals of relatively small size (none that would not work in a well maintained 40). They DO NOT SPECIFY SPECIES, only local, and they do not send the same specific species in either of the two complex all the time (I was expecting abdopus and got macropus with Puddles. I adore this complex but had wanted a diurnal octo - would not trade Puddles for the world though). You do not have to worry about briareus if you order one marked Indonesian as the origin but you DO have to worry about it if you choose (when it is available) the Caribbean option. Both are shown as options when you place an order but both are not always available.
