All info needed above, if the water is there, they will drink from it, you will not allways see it, (im not guarenteeing you will ever see it I haven't as yet) but they will drink with time.
Some like water droplets. Mine will sit in their moist hides after i've misted them and just lick, lick, lick, lick, the sides where the condensation is.
Mine loves to lick the wet edges of the bowl, and the splatters from when I've refilled it. I don't usually see him drink from the "deep end," though he will sometimes stand in the water when it starts getting low.
