This now poses an issue in my tank. I have a penninsula and can see the fish seeing themselves in the end of the tank when the light conditions at certain times of the day,  create a mirror for them... 
Who would have thunk...man, learn something new everyday. Only been doing this for a year and something as simple as that, i did not know.

 While it is known they can attack their own image I have not heard of any fish fighting to the death with themselves although I have read that they can exhaust themselves to the point where they can become targets themselves leading to possible injury and possible death from said injury
