Here are some pictures of my 30 gallon tank. I just finished changing the setup. I chaned my gravel from black-and-blue to a natural-colored gravel; removed old decor and added stones, shells, and rocks instead (found in the river); and added two pieces of driftwood (which were soaked and boiled for a couple of days before putting them in the tank). The fish are temporarily in a quarantine tank, waiting for the water to stabilize in the main tank. I can't wait to see if they'll like their new home!
