I really need some help guys. I just bought a octopus from a friend and I can't seem to figure out what's wrong with it. My friend said it was the rare Caribbean headless octopus. It has five arms but seemingly no head. It's skin is quite bumpy, however, it seems to find its way around the tank fine. It also has no eyes or sensory organs. I'm kind of confused on how it's alive. It seems to respond to shrimp pellets and its arms are long with suckers. I think I may have been dooped. Any help?
