Hi everyone. A few weeks ago I purchased a waterdog, and it has morphed pretty swiftly! Its gills are nothing but tiny little bumps on the side of his head. I've been keeping him in a completely aquatic setup so far, but I'm not sure if it's time for him to make the change to a more terrestrial one. If so, I plan on using a soil substrate to make a vivarium. Would it be safe to use soil out of the yard or is it advised that I go buy some from somewhere? Also, what are some recommended plants that go well in a tiger salamander set up? Thanks!
