I've noticed that my snake will swim around in his water bowl, to under water and swim around.. Of course he cannot move much nor put his whole body in the water bowl and still swim around. Last night I tried letting him swim in the bathtub with about a half inch of water and he just sat there. Today I put about 2 inches maybe less of water in my bathtub and he absolutely freaked out and crawled out of the bathtub. Am I doing something wrong? What should I do?
