Hello! My thermometer has not been sticking to the side of my tank. This problem recently developed. It’s attached by a suction cup. Should I just give up and buy a new one?
 
If you are talking about those $3 Amazon ones, then yes, either buy a new one or a better one. It will fall off again, float around and eventually break and have broken glass all over your aquarium. I know from personal experience :)
 
I’ll head to the store sometime this week! Thank you for the help!!![emoji846]
 
My guess is that your fish may be knocking it away from glass, my Mbuna cichlids are notorious for knocking mine away.
