Most people try to create as natural an environment as possible and moon lighting ties into the theory (check out Rehypes build with his led lights). Secondly, most bad things in our tanks like to come out at night. Without moonlight you will not be able to see if anything is attacking/eating things in your tank. Those are some more practical reasons, we have them on 2 out of our 3 tanks. From a purely fun aspect, they make your corals look pretty cool.
