Well Occy has come out of his/her lair there are no eggs that we can see she is right up the back of the tank up the top behind the power filter instead of her normal browny cream colour she is pure white and her breathing seems laboured she has been up there for about 8 hours now and hasnt moved at all, she is still alive as we can see her breathing so it is very disturbing to say the least, I just wish I knew what was going on with her.:cry:

I see you have had her for 8 months. She may be nearing the end of her life. Have you checked your water quality?

Im not sure if it is a female or male but it is still up the back of the tank its tentacles are all spread out and it has tucked itself into the membrane in between. One of its tentacles looks like the end has fallen off and the is flesh hanging from it. It has not eaten for 3 days even when it is offered I think you are right I dont think it is long for this life which is really sad it is still pure white. We have the tank professionally serviced once a fortnight we only use proper sea water and other than the salinity being a little high the tank is perfect. I really miss him already :frown:

ozoccy,
Unfortunately, most only live in an aquarium for about a year. It is believed that the life span in the wild is about the same. At eight months in captivity, the chances are high that is his/her time and is the natural way of it. Your symptoms definitely sound like old age. You might do a search on senesence on TONMO and octopus senesence with a search engine but here is a good article referenced by another member in an earlier post:

This is definitely the worst part of being a ceph keeper.

If your octopus is showing arm loss, I would guess that it is a male. Males and females both go through senescence and both show very similiar characteristics during during this time. The main difference is that females will remain in den brooding their eggs until they eventually expire while males will become very active and autophagy occurs. If that one arm looks severed, the octopus may have eaten it.

(As an aside, octopus have arms not tentacles. Tentacles are the feeding body parts of squid and cuttlefish.):sun:

I wonder if the male octopus display any preference towards specific arms during this phase?? ie, is the hectocotylized arm eaten first??

I didn't think autophagy was common in all octos that are near death. I thought if they showed signs of autophagy at all it is a bad sign and you aren't going to look forward to sterilizing your tank afterwords.

While I will not say that it occurs in every species of octopus, and in each individual male, it is quite common in regards to senescence. If autophagy is occurring and the specimen is not near the end of its life span, then you would begin looking for other possible reasons.

I have observed this to occur, at least in captive male GPOs, on multiple occasions while the animal was showing clear signs of senescence.

Greg :coffee:
