Welcome to AA, amoaudio!
Your post reminds me of the movie, "Insomnia", where Al Pacino's character had trouble sleeping because he was in Alaska during summer, when the sun never sets.
Having the light on all the time is unnatural and stressful for fish. The fact that they aren't showing signs of stress is a sign of how adaptable they are. Plants also do better with a period of darkness. Photosynthesis has a light cycle, where sugars are built from CO2
and light energy; and a dark cycle, where those sugars are broken down for energy the plant can use.
I would recommend getting the timer and setting the photoperiod for no more than 12 hours. The fish will lose their coloration - this is normal. When the tank light is off, make sure there aren't any bright lights on in the room. I think this is what is spooking your fish - the reflections caused by your room lights in a darkened tank that they just aren't used to. Your fish adapted to total light, and they will adapt to a more normal photoperiod.
I'd be curious to know what your plants do when they finally get a break from light cycle photosynthesis. I'm guessing you'll have an insane spurt of new growth. Please let us know - this sounds like a cool experiment in progress. 8)
