bowls. They need more space to perform. Goldfish don’t like being touched on their bodies. Goldfish are also sensitive to changes in water temperature.

However, if the tank is not well-oxygenated, it will not be able to breathe properly and will die. Goldfish are very sensitive to changes in water temperature. If the water is too cold or too warm, the fish will become lethargic and may not eat or drink at all.
This is especially true if they are kept in the same tank for a long period of time. Goldfish will also become dehydrated if kept too long at a temperature that does not allow them to regulate their body temperature properly. The best way to prevent this is to keep the temperature of your tank as low as possible, but not so low that your fish cannot survive on their own.

This can lead to a number of health problems, such as anemia (low levels of red blood cells) and kidney failure. Also, if you have a lot of algae growing in the tank, this can be a problem as well.
Another thing to keep in mind is that some fish are more sensitive to certain types of water than others.
