I have had my Russian tort for about 5 months now and haven't had any issues but this morning when I was giving him his soak, I looked in the water and saw something on the bottom of the container that looked like tiny grains of sand. As I looked closer the water had tons of tiny tiny worm looking things. I am not sure what I can start doing for him today until I can get him to the vet. I have never had this problem before with him and not sure what caused it and more important what I can do for him. Any advice would be greatly appreciated.
