Temperature

The Temperature is an important way to let your fishes think what season it is. Also, they have a different tolerance, on how low or high the temperature has to be. If the temperature is not between their temperature-tolerance, they will get sick and die.

How to change the temperature
In the Aquarium Info panel, you can not only change the decorations or ph-Value, but also change the temperature. It can be between 4 degrees Celsius and 40 degrees Celsius.
