Hey Jim,

Have you considered the possibility of night lights? By this I mean pre-positioned lights behind the coral in various alcoves and such. That way when you turn down both sets of lights (both foreground and background) these would come on and add a nice touch to night time viewing by casting light up from below the surface instead of from above. If you've ever seen a Koi pond at night with these kinds of lights, it's pretty cool actually (even though that's fresh water and this is salt, it really shouldn't matter).

Just a thought...
