I've always contemplated this: why aren't any moonlights red?

If the vision of underwater species is tuned towards the blue spectrum doesn't that mean that our "moon lights" are more like "day lights" for them? It's like when you use a red flashlight to see all the stuff that comes out at night. Why aren't there any red moon lights so that it seems pitch black to our tank animals but we can see them with our own vision?

Wouldn't that cause more creepy crawlies n such to come out at night for us to watch?
