Yeah I would remove those fish from the octopuses enclosure. I forgot that you had it in the fish fry box and not in the main tank itself. The octopus doesn't really have a place they can go to escape from the fish, and the fish will take bites at the octopuses mantle and prevent it from being comfortable in its space.
I would leave the octo in their box alone, and only offer food either via a stick feed, so you can remove the prey if they don't eat it, or add a crab or fish for a few hours, and then remove it afterwards for the night if it goes uneaten during those couple hours.
