The Thermometer Flat is an easy, accurate way to find out the temperature of your terrarium or aquarium. This handy device attaches to the exterior wall of your tank and offers readings in both, Fahrenheit and Celsius. Reptiles and amphibians are dependent on environmental temperature to regulate their body temperature and maintain proper health. Fluker's Digital Thermometer helps you establish as appropriate Environmental Temperature Range (ETR) within your pet's enclosure to help ensure your pet's safety, comfort and longevity. In addition, adhering Fluker's Digital Thermometer to the outside glass of aquatic systems (below the water level) allows aquarium owners to monitor the water temperature for aquatic pets.


Most amphibians can be maintained in an ETR of 70-76 F. They do not tolerate temperatures above 82 F. They should experience a night-time temperature drop of 5-10 F.


An appropriate ETR for desert reptiles is typically 85-95 F, temperate species 75-90 F and tropical species 80-90 F. Free movement between the warm and cool sides of their enclosures is essential. Reptiles should experience a night-time drop of 5-10 F.

Consult your retail pet specialist, veterinarian or the available literature to determine the specific needs of your pet.


Prior to mounting, place thermometer in "warm" side (basking area) of enclosure of 30 minutes and  compare reading with the specific needs of your pet. If area is too cool, use a higher wattage bulb. If too hot, substitute a lower wattage bulb. After establishing the proper temperature for the "warm" side, move thermometer to "cool" side of enclosure for 30 minutes and record. establish an appropriate ETR before returning animal to the enclosure.

Fluker recommends using two thermometers mounted at opposite ends of the enclosure to help you monitor the ETR regularly.
