Yes, you are right Eric, Jim does have it in the Marine Aquarium, and it works very, very well there. But solid color gravel appeals to me the most. I know how they look in a real tank, where you have the advantage of viewing from different angles, as long as the color does not hide the beauty of the fish, and brown or orange would do that. I have always stays away from the rainbow color gravel, make me think of ‘pute’ when I see it, sorry to be so graphic, but a two tone gravel of the same color works well I think. Just a thought,
