Hi there,
I have 2 of these guys and I've found the more sub, the more burrowing. Less sub=less burrowing. One of mine likes to climb at night, so I'd suggest a tall tank. They also love soaking in their water dish! I've even seen experienced big-eyed owners use paper towels for substrate to encourage the frogs to explore their enclosure more. One last thing: mine enjoy sleeping in vine-like plants on the walls of their tank. Best of luck, hope you enjoy these frogs as much as I do!
