They shouldn't get moldy due to CO2 production. They will also start to sink once they get water-logged and the ones up top will get submerged. But if you don't want to wait you could probably help them out by pushing them in with a sanitized spoon. In the future, put them in a grain bag or muslin bag with sanitized marbles or stainless steel pieces to keep them submerged.
