Healthy fish and plants
Fish depend on a suitable surrounding temperature because, as cold-blooded animals, they cannot regulate their body temperature themselves. Cold-blooded animals’ vital functions decrease as the temperatures fall. The right aquarium temperature is vital if they are to maintain their food intake safely and keep their metabolic processes functioning smoothly.
The fish’s ideal surrounding temperature varies according to their origin. The JBL glass thermometer helps you to keep an eye on the temperature.
The ideal temperature range is marked on the glass thermometer. A suction cup makes it easy to attach inside the aquarium. It floats vertically if not attached.
