I'm from Florida in the Usa and all the PETCO and PETSMART comercials and adds have 3 or 4 lionheads in a fish bowl.
I heard the rest from reasearching for my first goldfish.
This is why there are so many people out there thinking it is ok to keep a goldfish in a bowl. It is wrong.
GoldF(fish) need a proper tank with filter and aeration. I even provide a filter with airbubbles and some plants to our betta in a 7 l bowl.
