Mine climbs occasionally. I had one in a non DSB and he was climbing and out exploring way more (probably less comfortable and a little hungrier). So I redid the tank (the pet store held it for us) and once the sand bed was established we put him back in and now he only comes out when I scrub the glass. Other than that he'll surface and bury himself about once a week.
