hello. I have a sulcata tortoise. I'm currently planning his proper closed enclosure but he's in an open enclosure right now. Yesterday evening he used his water bowl and pooped in it. I wasn't home at night and arrived late, so I was too tired to clean it. At around 3AM, my mom woke up and saw that the tortoises water bowl was red. I didn't see it for myself though, since my dad washed his bowl before I woke up. I'm really concerned about it since he's also constantly climbing the sides of his enclosure throughout the day, and flips over sometimes. It stopped for a year but he's started it again. Is the red because his poop may have slightly dissolved into the water? Or is it something in his food?
