Opened tofu only lasts for 3-5 days before it goes bad. It is not recommended to store without water, so refill the container with fresh filtered water before resealing and refrigerating. 

Fresh tofu doesn’t smell bad. Any changes in the appearance or smell of the tofu may be from bacteria that potentially cause food poisoning.
