Wonderful news! Welcome to your new octopus, who sounds like it's had a hard life. I imagine you already know that aculeatus can drop an arm to confuse a predator.
Does it have a name? - I'd like to add your octopus to the List of Our Octopuses.
I hope you'll have some pics for us, too. This species seems to be quite friendly so you should have fun interacting.
That's nice to hear, I wonder could you keep a record of approx how long long the stumps are so that we could know how long a wild octo of the same speices has lost its arm according to the regrowth rate.
