i think more people do that than will admit!!!~ I have never had a live plant in any of my tanks.
~ My filter media gets rinsed in old tank water with every water change.
~ I never wash my hands before putting them into the tanks (unless I have cream on), but do afterwards.
~ I talk and interact with my fish daily. My husband thinks I'm nuts lol
~ My tank lights are on anywhere from 1 to 5 hours a day. Never more than 5. Otherwise they are off unless I have company. The fish seem to prefer it that way and the tank is in a brightly lit room so the fish are still visable whenever I want to see them or need to mess around with the tank.
