Beep Alarm, Fault Prompt: Our nano aquarium heater has safety features such as low water level shutdown and overheat protection. When the temp control system detects a malfunction in the equipment, it will give an error code alarm and stop heating to prevent any potential damage or injury. Note: Although the system will automatically turn off the power when a malfunction occurs, residual heat in the heating rod may melt the shell. Please handle it as soon as possible
Black Look & Mini Size To Hide Easily: The 50-watt Betta heater with a 4" long x 1" high heating element design takes up very little space, which could effortlessly fit into 5-10 gallon small aquariums and is also suited for shallow water turtle tanks
