Theresa Welch, owner of the Kritter's Den, stands atop a step stool and uses a suction tool to drain the water from inside a fish tank at her shop in Festus, Missouri on Wednesday, September 30, 2009. Welch is in the process of draining nearly a third of her tanks to reduce the cost of electricity and to minimize the amount of time it takes for her to keep them clean. With her being the only one on staff, it is nearly impossible for her to monitor the cleanliness of all the current tanks.
