Overview: Whether you won one at a carnival or bought one at the pet store, almost everyone has ended up with a goldfish at some point in their lives. The truth is, they're not as easy to care for as everyone makes it seem. Goldfish should not be considered a beginner's pet because of how much tank maintenance they require. Many people who get goldfish underestimate the amount of work it really takes to keep one alive and happy and they are not to blame. People are very misinformed about animal care and pet stores are partly to blame for that. Without the right equipment, keeping a goldfish alive for more than a few months is almost impossible.
