How long can goldfish live for when from a carnival?

The lifespan of a goldfish from a carnival can vary greatly depending on the species and the conditions in which it is kept. In general, goldfish sold at carnivals are relatively young, and if they are properly cared for, they can live for several years. Some species of goldfish, such as the comet goldfish, can live up to 20 years or more. However, it is important to note that goldfish purchased from carnivals may have been bred for specific traits that may shorten their lifespan or make them more susceptible to certain diseases. Additionally, the conditions at the carnival may not be ideal for the goldfish, which can also impact their lifespan. For these reasons, it is important to provide the goldfish with a suitable environment and proper care to ensure that it lives a long and healthy life.
