. For many amphibians and for most species of reptiles in terrariums, heating is necessary to create optimal conditions for these cold-blooded animals. In this case, the heat source should be located asymmetrically in the terrarium, i.e. in one of its sides. Only in this way can a wide temperature gradient be easily created in the terrarium, which will allow the animal to have the optimum temperature for him at the moment.
The emitter, especially powerful, must always be in the mesh box, and the mesh should not be very hot, in order to avoid burns in animals. To heat the inhabitants of the terrarium, you can use household incandescent lamps of various capacities. It should be borne in mind that a lamp with a mirror coating provides a deeper and more local heating. Various types of infrared lamps are also widely used in heating terrariums. Some lovers use insulated flexible thermocouples.
Any heat sources used (especially if it is without its own mirror coating) should be equipped with a reflector, which allows you to create a well-heated area under them in the right place. Heating can be regulated manually, following the thermometer in the hot and cold zones of the terrarium, but it is better to do this with the help of various temperature controllers. Directly in the place under the heater, it is desirable to arrange stones or plates that have good heat capacity and therefore contribute to a more uniform heating of the animal both from above and below. In addition, such stones remain warm for a long time after turning off the heating, which eliminates sharp temperature fluctuations in the terrarium.
A number of species, most often animals with twilight or nocturnal activity, need heating from below. For this purpose, it is desirable to arrange the thermocouples in the soil. Some reptiles also need night heating. In this case, shielded infrared lamps or photophonaries, as well as flexible thermocouples or ordinary incandescent lamps, covered with a tin cap for shading light with only small holes, can be used as sources of heating. Temperature control in the terrarium must be carried out using at least two thermometers, one of which should be located near the heater, the other in the opposite part of the terrarium.
Small ponds available in terrariums can be heated with incandescent lamps if needed. Water in aquariums that contain aquatic amphibians, heat-loving freshwater turtles or small crocodiles can be easily heated using various aquarium heaters.
When arranging heating and lighting in a terrarium, special attention should be paid to safety precautions related to electricity. The insulation of the wires should be undisturbed, water should not get on the wire connections (if they are not hydrostable), exclude the possibility of direct contact of animals in the terrariums with the wiring Rodents pose a serious danger to the wiring, and some types of wire sheaths are eaten with mice and rats with special pleasure.
