I'm a big fan of cork bark for frogs, toads and snakes. It won't rot, and so far all the critters I've tended to love this stuff. I'm also going to go with a planted tank for the WTF. I have one for my toads that is going great with 6 bufos, spring tails & isopods to keep it clean. I also have another one that just has plants but plan on adding a mantis this spring. It looks like the viv's for GTF are very similar to WTS, just little warmer and a little more humid. Now I just need to find a reliable place to purchase the WTF.
