Just added two algae shrimp to help with cleaning as well. Also, just finished setting an aquatic area in a 10gal tank for my dwarf pyxie. I think I will keep it fish-less maybe add some inverts or something and the underwater filter is on the way. That 9$ Amazon.com: Hagen Elite Underwater Mini Filter, UL Listed: Pet Supplies is freaking awesome they just recently bumped it to 13 bucks but is so worth it. It moves water around like a much larger filter and does a good job could easily handle a 10gal tank.
