An essential piece of equipment for any aquarium fish are cold-blooded animals, which means they cannot regulate their body heat like human beings and other mammals. They need the right external temperature to survive, irrespective of whether they are in the open sea or inside an aquarium. The temperature in the seas and oceans remains fairly constant through different times, so fish have the natural ability to survive here. However,freshwater and saltwater aquariums are different because they are man-made and not a natural habitat of fish, so owners of fish tanks should take more effort to maintain the right water temperatures.
How can you control and monitor your temperature? By using a thermometer - see our range of them below.
