This. I worked at a petstore and constantly had to warn people that the bowls were trash and it WOULD outgrow the bowl. Nobody listened and they either ended up having to buy a bigger tank later or it died.

I also had an old customer who had one single goldfish in a large tank. He told me he had it 20 years after winning it at a carnival and he was a full foot long and loved bloodworms. I love people who treat fish like living things and not expendable.
