Hobby Nature Aquarium An underwater, living zen garden I designed with my roommate for a space in our house. We took insipration from Takeshi Amano, the pioneer of the nature aquarium. A 12 gallon, freshwater nature aquarium my roommate and I created. Starting out - setting the landscape for the rocks with aquatic soil. Creating a "hardscape" with Seiryu stone. Where is your eye natually drawn? The tank after 4 months! The plants are supplemented with CO2 and fertilizer. A red cherry shrimp grazing on some algae. A nerite snail chuggin' along on a rock.
