on Saturday i decided to go to my local pet shop and pick up 4 young mystery snails. the employee accidentally dropped all of the snails on the floor. i didnt notice the cracks so i just went with it, but today i took a closer look and saw the cracks. most of the cracks are just hairline cracks, so that gave me some relive. there is no cracks that show the snail itself but they are pretty bad, im worried water and bacteria might have gotten in? how do i fix these cracks? super glue? what is the safest for this situation? could i have some advise?
