It has been theorized that performing water changes with slightly cooler water promotes breeding... The thought being that it simulates cooler spring rains. I've often wondered if it wasn't just the influx of 'fresh' (or fresher) water.

Although night temperatures in the tropics may be slightly less, I'm not so sure that water temperatures fluctuate that much. Probably not as much as a when there's a heavy rain.

I don't see much, if any, advantage in lowering temperatures at night and I have not heard of any experts claiming it.
Maybe a better idea is shooting for and maintaining the lowest practical temperature for the species you have.

I have always had good luck with consistent 76-78F.

Tank On, Mike-
60g Marineland Community, Finnex Planted+ 24/7, Silica (pool filter) sand.
10g, 29g, & 37g fry grow out tanks, 110g stock tank.

What came first, the chicken or the egg. It was the egg, but not the egg from a chicken.
