That's a good point but a little bit incorrect. Fish in general don't respond to the amount of light but rather the differential. Therefore as long as he puts day lights on durring the day and the moonlight on all night every night, they will think that that is what night looks like. If he only put on the moonlights some nights that could be a problem but why would he do that.
