Hygger Mini Glass Aquarium Heater Adjustable LED Digital Temperature Display Small Tank Heater for Turtle Betta Fish Bowl with Protective Guard 50W. Keep your aquariums/fish bowls at the right temperature with hygger mini heater.
I’ve had this heater for the past few days, and it keeps the temperature in my tank very consistent! Just set your desired temperature and you’re good to go! Very simple operation and the automatic temperature regulation kicks in as soon as the temperature in the tank drops a degree. Very impressed!
