Healthy fish and plants
Fish are dependent on the right ambient temperature because being cold-blooded animals they are not able to determine their body temperature. The life functions of the cold-blooded animals decrease with falling temperatures. The right aquarium temperature is therefore very important to maintain a problem-free food intake and a trouble-free functioning of the metabolic processes.
Depending on the origin of the fish, the temperature, they feel comfortable at varies. With the JBL glass thermometer you can keep an eye on the temperature.
The glass thermometer is marked with the optimal temperature range. Thanks to a suction cup It can be easily attached inside the aquarium. Floats vertically if not attached.
