I've got a dovii pair in a 180g tank, ever since i've had them they do nothing but attack the top of the tank, I'm guessing its b/c they see their reflection on the ceiling of the water(kind of looks like a mirror) and my male scrapes his hump on his head up pretty bad, but he keeps doing it over and over......anyway to get them to stop, btw they do it when light is on or off so I really dont know what to do.
