Hi, I got an all-in-one tank with a filter and a light. When the light is on in the tank but the lights in the rest of the room are off, the sides of the tank act like a mirror and he flares up. This is amusing for a few moments, but if I leave the light on in the tank and leave the room, I have a habit of turning off the room lights. I'll come back a while later and he'll still be aggressively posturing at his own reflection. Is this kind of prolonged aggressive response bad for my fish? It looks tiring at least If I leave the light on 24-7, will he eventually get used to his own reflection and not be bothered by it anymore? Thanks!
