You are seeing classic symptoms of senescence. Some animals last for weeks, others only a day after symptoms are observed. The clouded eye is also common. The fact that she is still eating is unusual and usually (though I have had a female of another species that did not) you would have seen eggs (even if she had never mated) before senescence was obvious.
I suspect Mister IS a Mister. I went back through the journal and found (post #97 on page 5) where you mentioned seeing an arm curled but I must have missed the post or my response disappeared (I had some problem with that at one time - reason unknown). The agitated restlessness is very common for males and on the rare occasion that females live past brood expected hatching. It is longer for males than the few females that survive that long.
Ugh, my heart... Misty was still for about 2hrs, getting smaller and pulling in on himself... crabs and other beasties were edging closer... and then he got up and did more laps... I cannot... ugh...
If you expect your aquatic pet to do something... but then it doesn't... you miiiiight have an octopus.
At this point, if you have a breeder net or your critter keeper, you may want to place him in a protected environment (allowing him to escape if he wants). The failing skin attracts the cleanup crews early.
Came home to find the pencil urchin wrapped in a leg. It is one of Misty's back legs, so it wasn't a sex thing.
He is still swimming and doing laps. Crawling around the sand and squeezing between rocks. Resting in or on top of the conch shell.
He does not stay put for longer than an hour or two.
