I recently bought 2 plants for my tank that has guppies, killifish & snails. They came with a heavy, gray, bendable strip that weighted them down, so I just buried the bottoms in the gravel - I really just bought them for the snails to munch on. Anyway after the plants were eaten I saved the strips and have been weighting my lettuce this way. My son saw what I was doing and insists the strips are lead. I read in the post about the broken thermometer that lead is toxic. Does anybody know if those things really are lead and if so will it hurt the fish?
