I am a plant junky. I love beautiful vivariums full of live plants. I want to put some in my toad's tank, though not overloading it like my tree frog tank. Right now, Clarice (our toadlet) is small enough that plants will work just fine, so long as she can still find the fruit flies. I know eventually she's going to be a BIG toad and start burying herself in the substrate during the day. What kind of plants, other than the moss I already have in there, can I plant that will withstand a toad's digging?
