OBTs are not "friendly" tarantulas at all. OBT has many meanings. I believe the actual name is Usambara Baboon Tarantula, which has changed to Orange Baboon Tarantula, and is basically now referred to as "Orange Bitey Thing" aka OBT. The picture I took of it, is in it's enclosure. I actually just use small acrylic boxes from Michael's (an arts and crafts store) and solder holes for ventilation. Add a little substrate (and sometimes pieces of bark or something) and viola. They basically move everything around, build tunnels, and web everything the way they want anyways, so I never have put anything extravagant in my tarantulas enclosures.
