yes I know very little about octopi, but I do know that the Mimic is rarely seen in the hobby. The only one I have heard of was a wholesaler who found one in a shipment he recieved that was sent by accident, they didn't even know it was in the shipment. So one of the owners or employees took it home.
There was an article in one of the magazines awhile back when they were focusing on Cephlapods that month.
How is the cuttlefish breeding going Rich, any luck? I always consider going into this part of the hobby, especially every time I see an octopus on the stock list for a wholesaler, but I hate the short life spans.
