Unfortunately I'm pretty landlocked or I'd collect them myself (the kids and I always have fun catching them at the beach)...
Last night I left a chunk of "fresh" shrimp in the tank in addition to splitting open two clams and putting in another crayfish minus 1/2 of each pincer. All of the offerings remain intact so I decided to bump the temperature up again. I did this late last night and then again this morning, a degree each time. The current setting is 60 degrees so at warmest the tank will get to 61 before the chiller kicks on.
I did see both of them out and wandering this morning and am questioning whether I have a male and female or two males with a missing hectocotylous. What I initially interpreted as new growth on the arm may have simply been me seeing the wrong arm.
Both look "good" from what I expect of a healthy specimen with good coloration, appropriate pupil dilation, and normal movement. I do wonder, though, if there's potentially an issue with having two octopuses in the same tank now. I have not been able to determine what aggression and territoriality these have in the wild since I can't even figure out what kind they are and to date I have not found two potentially healthy specimens (I buy multiples to give myself a better chance of success) but at the same time, I have not seen any sort of aggression between them. They have crawled across each other many times and I have yet to see any displays that would suggest unhappiness with having another octopus in close proximity out of them. I doubt that they are colonial like the Greater and Lesser Pacific Striped Octopuses as I am assuming that with them being a common food product that is harvested in such large numbers that this would not have escaped people's notice, but that doesn't necessarily mean that they are aggressive towards each other.
One way to determine if this is a causal factor in their not eating would be to remove one of them, but without a suitable place to put another one, I don't feel this is a good idea as getting them over the health hump is difficult to begin with. Has anyone experienced octopuses being stressed out to the point of not eating because they are close to another octopus? As I said, I would expect that if this was the case there would be at the minimum some posturing between the two, but there have been no displays that would lead me to suspect problems of this nature at this point in time.
