is he ok? My sand boa is drinking a lot of water then opening his mouth repetedly

(yea im new at this)

he seems fine but im wondering if this is normal, he drank A LOT of water

Did you just feed him prior to the drinking of the water? Does he have water all the time as well?

he ate 3 days ago, he has water at all times. maybe he didn't know it was water, ive never seen him near it till when i put him back and put him on the rim of it to see if he was thirsty. thats when he drank so much.
(i've had him for 3 weeks)
