>> Or just kill them.
Once upon a time in a restaurant in Japan I ate baby octopuses (octopi?) in plum sauce. They were about 4 inches long. Very good!
So Doctor Delbert Dumb and his spoiled son could raise them, kill them and eat them. Problem solved!
Calamari is great.
I hear in Japan they love to eat Octopus. That is why I said he should sell them to a Japanese restaurant.
