I have an aqueoun 10 or 15 w heater for my Betta and usually it keeps the temp in my Betta tank ant a balmy 82 degrees, which he loves. I changed the water yesterday and noticed that the temperature is at 88 degrees this morning. He doesn’t seem to mind, but it is supposed to shut off at 85 degrees and I’m wondering if anyone else has this problem and what small adjustable heater anyone can recommend as I was going to upgrade and use this one for his bowl and a spare.
