Aquarium thermometer

This digital thermometer is for aquarists who need to keep track of water temperature in a fish tank without placing a probe inside. It is mounted on the outside of the glass, so it does not add equipment to the water. It suits keepers of tropical and exotic fish whose metabolism and feeding depend on a stable temperature.

Why it matters

• Temperature control: Fish are cold-blooded and cannot regulate their body temperature themselves, so the water temperature directly sets their metabolic rate.
• Feeding and digestion: Physiological functions of cold-blooded animals slow down as temperature drops, which affects how well fish take food and process it.
• Species-specific readings: Preferred temperatures differ depending on where a fish species comes from, so a readable display helps match the tank to the species kept.
• Accuracy: The thermometer is designed for reliable measurement, and the adhesive mounting lets it be placed directly on the tank glass.

What it works with

The thermometer fits freshwater and exotic aquariums where the water temperature needs to be checked regularly. Because it sticks to the outer glass, it can be used with any tank that has a flat, accessible glass surface. Pair it with a heater or cooling device from the same category to keep the readings within the range required by the fish in the tank.
