I only have 4, but I've observed a range of burying behaviors in those 4 frogs. My growing female ornate never buries herself and follows/watches me when I walk into the room. But, she's also quite aggressive and will take food at any time of the day. My adult male cranwelli stays buried or hiding in his log most of the time, but has been coming out in the afternoon/evening lately now that it's warmer and he's hungry. My small fantasy half-buries itself no matter what. My new cornuta seems to have no interest in digging in the dirt at all. He/she is always in the pool or sitting bulldog style right next to it. When I had the moss (came with it) in it's enclosure, it sometimes wiggled into the moss. I'm guessing that the cornuta would love to hide in leaves if I put some in there, but it seems to see the dirt as floor.
