I am hoping you can help me. My turtle will not eat any vegetation. I noticed you recommended duckweed and the frozen cubes for aquatic turtles. I have tried both as well as romaine lettuce floating in the tank. I can't find the other aquatic plants you mentioned locally and I'd rather not order it online becasue the turtle may not eat that either. I have about 2 cups of duckweed in my fridge that is going to waste. Do you have any other suggestions? Thanks.
