Yvan...........My fishroom always has a light of some sort on all of the time.....never totally dark. Mostly I suspect it's so I don't trip over anything when I go in there when it's dark. However I do think that the moon and it's phases can and do stimulate F0 fishes for sure. I have absolutely no proof of that......it's just that Mother Nature has things so completely covered that a strong moon at night must help the females in some fashion! In particularly after watching the "Blue Seas" on the educational channel for the last 2 days............man............mother nature has sure got most of it covered! .......as far as guarding the fry....the females will do a good job in 99% of the cases but you can help her by not putting any real night time feeders in the tank.
