Im a new tort mom and I’ve got a baby sulcata who is about 9 months old and I’ve been soaking them often in a shallow tub of water that goes to about where the bottom of the shell meets the top. I’ve noticed that sometimes my tortoise will lay down in the water and blow bubbles with sides of their mouth. My tortoise keeps their head above water with their mouth slightly in. Should I lower the water more or be concerned at all? I haven’t noticed any other problems with my tort besides this.
