Review on 🐠 DaToo Aquarium Heater 50W: Mini Fish Tank Heater, 50 Watt Submersible with LED Temperature Display by Andrea White

I bought this heater because my mysterious snail and rooster lived in the arctic thanks to our air conditioner running at full blast during our beautiful Florida weather. It worked great initially, the temperature control function is good, it stuck to the wall of my small tank and kept the right temperature. But now it won't raise the temperature above 72 degrees (room temp), my snail died and my betta fish is making its way to the door. So. I'm not sure about this little thing. I liked it because it didn't take up much space and was easy to use, but I feel like it broke pretty quickly and now I have to return it and try something else.
