Look at O. digueti. I think the sizing and the eye papillae are a better match but would mean that she came from Southern California or Mexico.
I see no suggestion of a hectocotylus so agree with your feminine pronoun. At the end of her natural life, she will lay and brood eggs even if she has not mated. However, she appears old enough to have mated so you may have to opportunity to see eggs hatch and potentially raise one or two hatchlings. The chances of raising them are slim, regardless of egg size, A few dwarfs lay larger eggs that are not pelagic so the adventure will be interesting and I hope you will journal the full experience.
