I love this one!! I use it in all four of my cresties tanks. They are fabulous! And battery operated so I don’t have to worry about any cords or unnecessary parts. I did buy a pack of small suction cups so I could suction it to the side of the tank, but it does have a little kickstand if you’d rather use it that way!

Try getting jumpstart thermostats on Amazon and 2 pack Grove indoor hygrometer and thermometer put one on each side of his enclosure set the app to preferred(appropriate) temperatures
