New Betta keeps flaring from reflection

[tiffanieg1985]

I recently rescued a beautiful Betta from walmart and I noticed he keeps flaring in his tank. He keeps seeing his reflection in the glass and im afraid it is stressing him out. Is this normal for bettas or is there something I can do to to the glass. I put plants in the back of the tank so he would stop going over there but he just pushes past them and tries to fight his reflection. Is there anything else I can do or will he eventually stop?

Mine did the same thing when I first brought him home but he stopped after the first few days

It helps to keep a light on in the room. A lit tank in a dark room reflects a lot.

Do you have a backing on your tank? I put a plain black one on mine and did not realise it was like a mirror so I removed it after a couple of hours.
