My betta flares at his reflection all day, every day. Is this healthy? Should I let it be? I covered 3/4 sides of the tank and he flares at his reflection on the front glass. I had tank mates for him, 3 small harlequin rasboras, and one night I saw him attacking them. So now all he does is flare at himself. I am thinking of getting shrimp to keep him distracted, but it seems like he would hunt them down & kill them all.
