Actually I would think it's just the opposite. Even though corals need the light fish settle in around the time the lights go on and off. I see it all the time as anywhere for 1/2-1 hour before the lights go off the fish are finding there hiding places, even when daylight saving is around and the clock are changed the fish still follow the same routine for awhile before settling in. Same thing in the morning the fish know when the lights are going to come.
In the ocean it probably never gets as dark as it does in our home, specially in say a basement. The moon and other light source give off light. I would think as long as the corals got the correct amount of light each day they would probably have no problem adjusting to the change in timing of the lights. |
