It has been well over a week since I last saw my octo. I have had it for over 3 weeks, now but have never seen him eat anything. I know he is still alive because the wall of shells he has covering his lair is rearranged daily, but he has not been seen for awhile. I have even checked when the lights are off, but even then I haven't been able to see if he actually comes out. There are several hermit crabs for him to eat and I even went so far as to purchase an emerald crab as a rather expensive treat, but it has been alive and well for almost a week. The last time I saw him it was after I pulled his wall shells out of his den to force him out, but I don't think this is helping him get adjusted to his surroundings. I think it is not going to make it, but I hope it proves me wrong. The water quality is excellent, as I mentioned in my last post. Any suggestions will be most appreciated.
