So we all know that animals have a fight or flight instinct, and most bettas are usually fight. My old betta would fight with himself in a mirror as long as the mirror was there. But my new guy, Smaug, is less confrontational and I think prefers "flight." He kind of attacks the pink mirror then swims to the opposite side of the tank, then slowly comes back for round two, following his pattern of fight then flight.
So, when you hold a mirror up, do your bettas have any special or unique battle tactics?

If you are wondering, Smaug is in a 2.5 gal filtered, cycled, and heated aquarium. I wish I could give him something bigger, but I'm a college student that is constantly moving, and this is the biggest I can manage to move all the time.
