I was just wondering if it is a good idea to add moon lights to my tank? Also what do they do?

you can add moon lights if you want. they dont really DO anything. just light up the tank a bit, im a moonlight kind of way, of course.

it lets you see the nocturnal behavior in fish, also sets up some breeding cycles for fish but you need to do a lot more to actually sucessfully breed them

actually many corals need the wavelength of light that actinic blue lights emit.
if you want healthy corals that will grow and reproduce blue actinics are a must
