Reflections on bettas

[sharkweek178]

I mean this sort of literally. While setting up a betta tank, I noticed that the inside glass has reflections. Which makes sense if the inside is brighter than the outside. Kind of like looking out a window at night and the room is reflected in it.
Is this going to be a problem? What can I do about this?

Some Bettas will flare and attack their reflection, others won't. If your fish does attack its reflection, growing algae over the glass can help reduce the problem.

My betta see his refection, But he seems to know what it is, and doesn't bother for it. from a 45 view I can see his reflection is very good when the room is dark.

They might bug a little in the beginning, but they get used to it fast.
