wayne, I am glad you're not getting all up in arms with me; my goal was not to incite anything. flame wars suck.
steve, one more thought, if you do decide to set a 6500k food-acro grow tank (doooooooo iiiiit

), Maybe present some brown sticks to the filefish without changing your display tank's lighting. I'd be interested if there might be a preference to slower growing polyps rather than fast growing polyps or vice versa. Wish we could somehow do a nutritional profile on the two to compare if the filefish does exhibit a preference.
