I moved into a neighborhood a year ago with a river as part of the backyard. I didn't have a clue how much I would love it! It's relaxing, beautiful, and the wildlife is amazing to watch. Because of this, I have become interested in building a river tank or a paludarium. I have never owned a tank in my life, other than a freshwater tank my husband set up for a very short time about 20 years ago! I would like to plant the aquarium, and later add fish. Money is a problem because I am unemployed. So, I was thinking about creating an eco-system from the fish and plants in the Alafia river, the creek, and the huge man made lake (retention pond) in the "back yard." Has anyone ever done this and achieved positive results? I know nothing about the fish or the plants, I am hoping since they live together "out there" they could survive in the aquarium together. Is this plausible? Would any of the river water be used, or all fresh water? Would I need clay pellets? I just am not sure where to begin. I am so excited about doing this, I want to start in a kitchen bowl! :grinno:
