Yeah, there are no bonsai kittens.

People do believe the fish in small tanks will stay small thing. Mainly because at some point the filters don't keep up with the fish, and they stop growing because the fish is unhealthy. Then the fish ends up dying. But hey.. it didn't outgrow the tank! Stupid people hurt my brain.

People will believe what is convienant to them. So they'll buy the fishbowl and goldfish, because they don't WANT to have to mess with a 50 gallon aquarium with filters and such. It's so much easier to think "Oh.. just a bowl" and not bother to find out what the fish actually needs.
