Since I got my betta he has been flaring at his reflection constantly. The only way I can get him to stop is by draping a sheet all the way over the tank to block out all the light. I've tried to put cardstock on the sides of the tank, dimming the tank lights and turning them off, and putting Indian almond leaves in to tint the water. Nothing has worked and my betta is really stressing himself out. And I can't even see him without him flaring and chasing his reflection against the sides of the tank. My tank is relatively cheap and I'm starting to wonder if maybe the glass is just low quality. I really don't know but I feel like I've tried everything. What should my next steps be? I can attach videos or pictures if needed but with the lights so low it is hard to see what is going on through the camera.
