JBL Aquarium Stick-On Thermometer

Fish are dependent on the temperature of their environment, as they are cold-blooded and cannot determine their own body temperature. The vital functions of cold-blooded animals slow down when the temperature drops. Therefore, it is very important that the aquarium is at the right temperature to ensure that feeding will not pose any problems and that the metabolism will function perfectly.
The temperature at which fish feel comfortable varies depending on their origin. A JBL digital aquarium thermometer allows you to monitor the temperature.

The JBL digital aquarium thermometer is extremely accurate and simply sticks to the outer glass of the aquarium.
