Riddle me this:
Wouldn't my inverts/corals suffer if there was enough stray voltage in the tank that my clownfish is being effected that much by it? My corals have been growing like mad.

It probably is not stray voltage. I only mentioned it because the fish hides when the lights are on. If you wanted to test this then leave the lights off one day with all of the room lights on so the tank gets some light and does not go into night mode. If fishy is swimming around normally and not spooked then have another look at your lighting system.
