I know that it is not abnormal for snakes to lay in their water dish, as this can be used as a cooling mechanism and what not... but I was cleaning cages this morning, and noticed that my new hypo female was laying in her dish, with her head under the water. I was afraid at first, as none of my other snakes even go into the water, rather, just drink from it. I know that snakes can stay under water for a certain amount of time (as I do research with water snakes at college), but should I be worried if my hypo makes a habit of staying underwater for a while? Any advice is welcome. Thanks.
