When I put the floating mirror in my tank for my Betta to flare at, he often does a ritualistic dance around the mirror which usually includes circling, flaring and pecking. The other funny thing he does is the tail slap, He turns on the mirror and slap it with his tail fin. It's a jerky motion and is quite amusing.
Today he started tail slapping me? I was having a stare down with him and he did his usual flaring at me. Then he turned to his side and slapped the side of the tank with his tail.
Take that, human!
Does anyone else's boy do this?
