Its cooling down a little recently, and this night I noticed the temperature in my tank fell a little below 75. So I guess its time to find a way to heat my tank. My frog is on eco earth in a 10 gallon glass tank without a lid. I dont have heating in my apartment, and right now the tank temp varies from 85 during the day to around 75 during the night, but in winter it can get like 60 degrees inside sometimes.
What are the options to heat my tank? My frog is albino.
