Thi is an interesting idea, however, doesn't Pa., get a cold spell in winter?
I was wondring about a northeastern biotope tank, and wether anyone has done it. I saw a tank done as a Texas biotope with plants and fish collected from the area, its part of the biotope tanks in the Aquatic Gardener's Association contest. Very nice. My concern with this idea is how northern plants cope in a tank. Dormancy period? etc....
