description The utility model relates to a heater which can prevent the water heating-up temperature in the fish bowl from too high. A thermostatic control device is arranged in the heater body, a thermal resistor and a temperature regulation variable resistor turn knob are connected by an external electric wire and the thermostatic control device. The power-supply line end of the utility model is provided with a double spring thermostatic switch and a warning lamp, and the thermal resistor can be arranged at the proper position in the water tank of the fish bowl. The variable resistor turn knob can be stuck at the proper position of the outer margin of the fish bowl by the sticking board at the back, when the fault in the thermostatic device occurs, the power supply can be cut off by the double spring electric thermostat immediately.
