I have a new 5 gal. tank with a lone betta. Today I put up a blue backing to the tank and now my betta is all puffed up like he sees another betta in there. is he seeing his reflection (I can't tell) and if he is seeing his reflection all the time is that dangerous to him? Maybe it's just a new introduction to his environment? Should I remove the backing? I'd hate to b/c then all the wires are visible.
Thanks for any help.

He also keeps a close eye on the necklaces that hang from a wall rack behind his tank. When I change them he notices. I guess I'm lucky to have a green wall behind the tank and wires off the side so no backing needed.
