My betta Zach is constantly chasing his reflection across the front of his tank. He does stop and go in other parts of the tank, responds normally to activity outside the tank, and eats well. I'm just wondering if there is a way to reduce reflectivity of the glass. I turned off the aquarium light and it is still reflective. Is there a possibility of the tank being backwards (like the front is supposed to be the back). Zach doesn't flare as he chases himself, but it's so constant. He loves movement, so maybe he just likes watching the movements?
