Much of this has to do with the reflectivity of the surrounding room when the tank lights are on & the room lights are off or dim.
I found that if a tank is in a very dark room that doesn't reflect much light back into the tank, the fish are very likely to see their reflections. But I put a large mirror in that same dark room which reflects tank light back to the outside of the tank, that additional light prevents the fish from seeing as many reflections.
