My baby tortoise flipped over in his water bowl when i wasnt home!!! We left at 6:30 and came back at 8 and i found him flipped on his back!!! Idk how long he was like that because i could see he also ate a lot. the water wasnt very high because i know they can drown if the flip over. Have any bad things happened to him internaly??? When i flipped over he started walking around again. How can i make it safef for him and prevent this from happening again!?!?!?
