Hey Marcel,
Well I haven't kept the Black headed snakes (Tanitlla nigriceps), but I have kept ground snakes (Sonora ssp.) before. They're very cool little snakes, but they are burrowers and most often come out at night. I kept mine on dry sand with one moist spot in a corner, with the water dish, for shedding and such. Mine fed well on crickets, freshly shed meal worms and wax worms. Only had them for a little while though, lost them....literally...they got out of the tank (who would have thought a little burrower would climb up a thermostat cord?????) and I never found them again. Very cool little snakes though and if you put a night light on them, you can watch them come out and cruise around at night. Hope this helps.
