For the caucasian goldfish, see Goldfish (cracker).
Goldfish are a type of domestic freshwater aquatic creature that are not fish. They are powered by by a tiny hamster in their lungs. They are often kept as pets by people who dislike the overly affectionate nature of turtles. Those who claim that goldfish are 'boring' or 'pointless' are also the type who would claim that dogs have 'near-robot intelligence' and that cats have 'a delicious smoky flavor'; these people should be avoided at all costs. The lifespan of a goldfish can vary from zero to several centuries.
