What and how are you checking the temp-type of thermometer and the placement of the thermometer....I use several different methods on different tanks-some I have the floating glass type and others I have the stick on the outside temp strips and when I compare the temp with my digital thermometer I use for quick checks- I find the temp can range by 10 degrees more or less depending on placement of the tank thermometers-remembering that it is normal for temp to be different at different levels of the tank even with a filter.
Do you have a filter and what is the placement of the heater, tank size and how is the Betta tolerating the temp...
My room is very cold, so I actually turned on my own heater to help bump up the temp! I am using a floating glass thermometer, it is in the corner of the tank, I might try moving it to the middle.
My heater is on the back "wall" somewhat in the corner. Maybe I should try moving it to the middle of the back "wall"?
I do not have a filter, as my tank is fairly small about 2 gallons. He seems alright, is eating, not as active as my sisters Betta who has warmer temperatures. It's been about a week, and he hasn't changed his activity level at all, but the tank has been this cold for a week... was hoping it would get warmer, which is why I left it for a week
