I went with aspen because I heard the Dum likes to burrow - and sure enough, my little girl is always buried in the stuff. I put in just over an inch of depth (she's just a yearling).
I mist the enclosure because my setup is pretty dry. My girl makes piles up the aspen and then makes tunnels. I never know what the land scape is going to look like when I go in.
0.1 Pastel Lesser Platinum (BP)
0.1 Dumerils Boa
0.1 Indian Sand Boa (Sunset)
0.1 Kenyan Sand Boa (Anery)
0.1 Kenyan Sand Boa (Rufescen)
0.1 Kenyan Sand Boa (Paradox Albino)
1.0 Kenyan Sand Boa (Paradox Snow)
And a lot of Tarantulas
Here is a pic i just took after switching it. He is still kinda unsure of it i think. I put a layer of newspaper under to make cleanup alot easier.He used to burrow in the cocofiber whenever i put fresh stuff in, the aspen seems alot better for burrowing so i think after a day or so he will like it.......i hope,lol.
