Nice picture. I have lost several hitchhiker crabs that came on my first shipment of tbs rock to an octopus that also tagged along for the ride. I am completely new to saltwater, so was a little concerned about his longevity in my tank. But the rock arrived before Thanksgiving, and the octopus is still apparently doing fine. The only down side is he only comes out in the middle of the night so my kids never see him.
