Aquarium Background Submersible?

[Hmongol]

Hello, i have a 5 gal acyrlic tank for my betta and it seems to show a great deal of a reflection for my betta as he is always constantly flaring at the back. I was wondering if anyone can tell me if one of those background at the fish store can be submerse so it doesnt have a reflection. If anyone knows another way around it, it would be much appreciated. Thanks in advance.

you could try a 3d background. But it could take a week to fully be ready. Might I suggest painting the back with acrylic paint. Those in the shop cannot be submersed
