So my dad got me this beautiful betta. He is in my 20 gallon high. My problem is that it's quite an old tank so I don't know if they still make tanks like this anymore but the back side of the tank is like a mirror and you can see your reflection in it. So it stresses my Betta out and makes him flare. So I was wondering if there is anything I can do to fix this (without having to take all the water out of my tank.) Help ASAP would be great! Thanks!
