This is why I have a 3 foot rule around all my tanks LOOK but Never touch or you leave the viewing area I use too do preschool and kindergarten tours at my wifes request I LEARNED REAL FAST so now I set up perimeters, kids get to view thee tanks and I get alot of peace of mind and the parents understand that they are MY Tanks which I take great pride in and are thankful the kids get to learn about aquariums, fish and parameters . It has been succesful for ten yrs and ongoing.
