Have a look at these pictures. You are trying to determine if the octos could be the same (I am thinking this is about the same sizing but neither pictures have reference points). Aculeatus will be much less robust, particularly comparing arms to mantle girth.
Glass dancing during the day is typical of Aculeatus adults but not a telling factor as other species will do this as well. Additionally, it takes a good two weeks for them to initially acclimate and then maybe 2 months to defend a den so I never expect behaviors I first see to be continued.
