Hello! I'm new to the site and unfortunately have to start off with some bad news. I came home from work yesterday to find my juvenile striped octopus, Oscar, had lost two arms. The only explanation is that a fiddler crab I introduced as food for Oscar got more aggressive than I'd ever seen him and attacked the octopus while Oscar was sleeping (he seems to like sleeping on the bottom of the tank, unlike my last striped who hid under a rock or slept stuck to the side of the tank out of reach). Anyway, the crab has been dealt with, but my question is how long will it take for the arms to regenerate and is there anything special I should do while he heals? I feel terrible about my miscalculation regarding that evil crab, Oscar doesn't seem to be able to swim and spends most of the time under a rock out of sight. Thanks, any advice you could give would be greatly appreciated!
