I set up my Micro Aquarium by first putting mud and leaf debris into the tank. I then put water from the French Broad River in the rest of the tank. I then added the aquatic plants Utricularia Gibba from Spain Lake and Fontilnals sp Moss from the Holston River to the aquarium. The end result was a finished Micro Aquarium. I did not see that many organisms in my tank, because they have not been given a proper amount of time to grow. I did see a mosquito larvae and a flat worm around the the plants in the aquarium. Both organisms were moving around the plant.
