hydrophyte: What type of water do you use? I always had a similar riparian setup (but nowhere as nice) for newts and fire belly toads in my classroom before I retired, which the kids loved. (No photos though) I also had a pond with fish, turtles, crawdads, and tadpoles (photo). My problem was white mineral-lines as the water evaporated in the tank setup. Your setup is pristine. Do you use rainwater?
