My octopus has been acting very strange lately. First of all he has not eaten in 5 days. He always wanders around like he normally does when he wants food but when I offer to him he has no interest in it. The second thing is that the very tip of three of his arms are missing. It's only about a half a centimeter but I'm worried it might be autophagy. Any help would be much appreciated.

Thanks,
Ben

How long have you had your octopus? The ammonia should be at zero. Is he trying to climb out of the water by staying at the top of the tank? I would do a waterchange if you haven't already. Good luck!

I have him for about 5 months. He hasn't been rtying to climb out of the water either. Infact he has been staying more near the bottom lately.

I would definatly do a water change. Tests are not always accurate, and it may be too late by the time your octo does try to climb out.

Yeah I will do a water change tomorrow. I'm concerned about the fact that he is missing the tips of his arms though. I suppose I should wait and see. Does this sound like autophagy to anyone who has dealt with it before?

Thanks for all the advice.

It doesn't sound like autophagy..............but it does sound like either a water problem or senility. In autophagy they tend to bite the arms off at the base.

Do a water change ASAP. IF things don't improve it may be old age......sorry

Autophagy is literally self eating! The octopus eats it's own arms. Its incurable and highly contagious (to octopus....haven't heard of any instance of octopus keepers eating their own arms and I don't think my nails count!!) and always fatal.

What is autophagy?
be warned, don't do a Google search on autophagy unless you have a strong stomach!!! I did a few years ago and it can be pretty grim, its not just octopuses that do it.

Okay, wait a minute here?
This Autophagy thing is a bit odd.
Am i understanding this correctly?
Not only will an octo eat it's self, but the act of eating it's self is
contagious to other octo's?

You are indeed understanding correctly. This is a contagious disease. the jury is still out concerning the cause but there is some suggestion that it is (in octopus at least) a prion (mad cow disease is caused by a prion), which is smaller than a virus and can sit dormant in cells (perhaps in the DNA) until something triggers it. Common triggers can be stress, poor husbandry.............or ..................sometimes the trigger isn't identified.

I'm assuming that the prions (or whatever!) can survive in aquascaping etc as without major sterilization of tank and equipment the next octi resident will get it too.

Thanks Jean, that was so well written, even i could understand it!!
I did some reading about prion's and ended up in wikipdia reading about
the canabalistic Fore' Tribe in Papua New Guinea. scientist have found the same type of disease in humans. I have heard about the existence of a canabalistic tribe, but had no idea it was caused by disease. I thought it was based in some religous practice. So, not only did you answer my question concerning Autophagy, but you aided in the removal of Papua New Guinea from the list of places I would like to visit!LOL

Okay, I think you need to revisit Wikipedia and read the article again. The disease kuru is believed to be caused by a prion, and is spread through the act of eating the dead in the Fore. Consuming their dead is a cultural practise, and is not related at all to the disease or prions. Just a point of clarification.

Cheers!

OK folks, now you've gone and done it! I'm going to have to dig out my old copy of Dream Park by Larry Niven and Steven Barnes. For those of you whose SF Geek gene isn't as fully expressed as my own, Dream Park is a 1981 novel in which the Fore' and kuru have a significant role.

In addition, the hero is a guy named Alex.

Edibly yours,

Alex
