Can I do this? [Hermit ]?

I was playing outside one time with my nephew when I saw a long branch that seemed to be cut through the middle, as well as a "drift wood" feeling thick/small stick/log thing. I brought both inside and put them in my soon to be Hermit Crab Aquarium. I cut up the long branch so I have several of them, and put the other drift wood thingy at a slant. Can I do that? I plan on eventually buying artificial twisty branches as well as real driftwood instead. They're going to be in a 29 gallon aquarium with 4-6 hermit .
