I have a Common Snapping Turtle who has about a 3 inch carapace, housed in a 40 gallon breeder tank. I like to keep live plants in the tank with her, as it helps with water quality. I am wondering if anyone has found a good way to protect the plants. She doesn't eat them but she will walk all over them and sometimes bite at them. She also likes to use them to hide under. Any ideas of good plants or ways of protecting the plants from her would be helpful. (I know she is destructive and most people can not keep plants with Common Snapping Turtles).
Try fencing the plants away from the turtle. You could try building a fence around the plants with something like chicken wire, or the plastic equivalent thereof or nylon mesh zip tied to some steaks. You could steak these into or bury them in the substrate the plant is growing in and then have them extend well above the water line so the turtle doesn't go over or under them. The turtle won't really be able to hide in the plants any more but at least s/he won't eat them and they can help with water quality.
