How come goldfish die easily?

There are a few reasons why goldfish are considered to be easy to kill.

* Small size: Goldfish are relatively small fish, which means that they are more susceptible to environmental changes than larger fish. For example, a small change in water temperature or pH can be fatal to a goldfish, while a larger fish might be able to survive.

* Delicate immune system: Goldfish have a delicate immune system, which makes them more susceptible to diseases. They are also more likely to develop health problems when stressed, such as when they are moved to a new tank or their water is not properly filtered.

* Common misconceptions: There are a number of common misconceptions about how to care for goldfish, which can lead to their untimely death. For example, many people believe that goldfish only need to be fed once a day, or that they can live in a small bowl without a filter. In reality, goldfish should be fed a diet rich in vitamins and minerals, and they need to have a properly filtered tank with plenty of space to swim.
