I took down my too-big 20g long aquarium, which I didn't really have room for. I set up an oddly shaped for it's size tank that I believe is a seven gallon tank in its place. I'm not an aquascaper artist, but I tried atleast to emulate a decent design with some random plants I bought at the store the other day and that I took from my 20g. So far I'm only adding pres. CO2. I'm going to see how it does and add nutrients as needed later.
