Healthy fish and plants
Fish depend on the right ambient temperature because, being cold-blooded animals, they are not able to adjust their own body temperatures. The vital functions of cold-blooded animals decrease with falling temperatures. The right aquarium temperature is therefore very important to ensure the animals maintain their food intake and guarantee a smooth continuation of all metabolic processes.
Depending on the origin of the fish, the temperature they feel comfortable at, varies. With the practical JBL Hang-on aquarium thermometer you can monitor the temperature in the range of 0 - 40 °C.
The thermometer with the precision capillary, made in Germany, has excellent measurement accuracy. Just hang it over the aquarium rim.
