How should I handle a fish that hates light?

I have a very nice, healthy Aussie lungfish...24 inches long, eats well, etc. I have had him for a couple of months. He lives with about 25 rainbowfish of various kinds. The tank lighting is just a single strip fluorescent bulb (48 inches on a six foot tank) so it is hardly blinding. Quite dim, actually, but necessary to appreciate the great colours on the rainbowfish. Ambient lighting in the fishroom doesn't bug him at all. He just sits on the bottom, moves around occasionally looking for food. But when the light is on above, he gets restless and annoyed, rushing around, banging into glass. Not a panicky bolt immediately, it si not that the light startles him, but just, ten or twenty seconds, the rushing around starts like it annoys him.

So I guess my question is should I just accept it, or should I turn the lights on in the morning and off at night and just wait for him to get used to it?

It is a good suggestion and pretty much what I was thinking as well. Which leads to the next question and maybe I will start another thread as this one doesn't seem to be attracting a lot of interest: what are some ideas about creating a shelter for a beefy two-foot Aussie lungfish?

Tank is a 200g (26 wide, 25 high), it is fine for now. Other fish are a couple of inches long each. Good suggestions Oddball.
