I recently purchased a heater for my 3 gallon tank (will be upgrading to a 5 or 10 gallon sometime later this week). It is in a plastic holder that allows it to be suction to the tank wall and my male Betta will not stop flaring at it. It has a small opening on the front to show it's on and the temperature. I'm worried that it's stressing him out since he continues to go flare at it every 2 minutes at the longest. I thought at first he was just asserting his dominance and thinking it's in his territory but i'm afraid that he's flaring that much at it. Should I try to hide it in the new tank?
