Thanks. He's a good looking betta, even though he's from Petsmart.
I never had isue with this heater, it's rated up to 10 gallons. IT shurts off, it's just that my room is in the mid/high 70s. The room's temp is keeping the tank at 76 right now. When heater turns on, it warms the tank to 82/84, a bit to high for my loaches.
