When I was a kid, my mom and dad built a new house and had a large built in aquarium in the living room.I caught fish and brought them home in a bucket to stock the aquarium. Some lived and some didn't but numerous times I would hook a fish too deep and cut the line. Within a week or 2 they would cough the hook up and it would be lying on the gravel. Usually rusty.
A built in Aquarium piped in to the utilities is a very entertaining feature in a house.
