Hi there! I keep Maggies (the fatter cousins of Whites) and GTFs so I know what you mean about needing plants that can take a beating!

I had pothos but they eventually became too fragile for my big fatties to sit on, though I use it in my GTF enclosure and it stands up to them somewhat!

I really like Bromeliads because they're so tough, I just clip off the pointed ends with nail clippers for the sake of fat frog safety. Birds nest palm is always a winner across all species because it's so tough and holds water well. I also can't resist a lovely bird of paradise in my 4ft tall enclosures because... Well pretty. Babies tears looks beautiful if you use a peat base and does well in low light. And who could forget the beautiful peace lily, Spathophyllum!
