How could you incorporate the dimmer switch to mimic the sun rise and sun set without manually do so?

You can't use a dimmer with florescents.

You can, however, get timed dimmers.

Those neon are so . . . bright! They look almost purple when near the surface! So awesome!
Byron, In my ten gallon with female bettas when I turn the light they never look stressed, ever. They dont get frantic or anything, just beg for food they do whenever somebody looks at the tank. Is this normal?

If there is sufficient ambient light in the room when the tank light comes on or goes off, fish shouldn't be bothered.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

I think it depends on the fish too. My betta never stress, but my cories will go nuts if I turn on the light in a dark room.

taking a break from fish-keeping.
3 lovely male betta still keep me company.

Yes, and tetra really don't like the lights suddenly being switched on, either. I actually try very hard to make the lights in my home kind of turn on and off gently for all of my tanks. . . First I open a window shade, then turn on the overhead lights, before finally turning on the tank lights. Same in reverse at night, only the window-shade is replaced by a dim lamp, or a light in the next room (depending on which tank it is). I don't know if this helps them or not, but I TRY!!!

When I turn it on or off I usually have a light so I can read in the morning, soit is not pitch black
