Water is essential for goldfish for a number of reasons. First, water helps to regulate their body temperature. Goldfish are cold-blooded creatures and need to rely on their environment to regulate their body temperature.
Second, water is necessary for goldfish to excrete waste. Their kidneys remove toxins from their blood and release it into the water through their gills. Third, water is necessary for goldfish to breathe.
They absorb oxygen from the water through their gills and release carbon dioxide back into the water. Finally, water provides goldfish with a medium in which they can swim and explore their environment.

Conclusion
Water is essential for goldfish and without it, they will die. Goldfish are very sensitive to changes in their environment and water is a very important part of their environment. It is important to make sure that the water in their tank is of good quality and is the right temperature.
They also need to have a good filtration system in place to keep the water clean.
