Hiding betta's reflection

[Salty&Onion]

Noticed this a bit time earlier but haven't been concerned. He is pacing, not sure about this but he's sometimes to be seen swimming from side to side on left tank wall and also sometimes spending his time at the back of the tank, sometimes flaring. How do I hide his reflection?

You could try taping a piece of paper over one of the sides and see if that helps.
Is your betta new? When I first got mine, he paced a lot. But, once he settled about a month later, the pacing stopped.

Thought we sorted this?

I don't know, I just saw this thread had been here for a while so I thought I'd answer. Was this already sorted? If so, the thread should have been deleted.

We generally don't delete threads.
