B. vagans and B. boehmei are both terrestrials and from the same genus. My vagans used the burrow i made for it in the cup. Didn't really expand on it too much except added some webbing. Just chilled in a hole that i made for it lol. My boehmei has built itself a ton of tunnels. I just put it in a cup with dirt and a water dish and he took it upon himself to do all the re-arranging and stuff. Same genus, two very distinct personalities lol.
