My laeotropic snail sometimes has swollen head. She seems to want to mate. Last night I put her and other snails in the same cage. Then, the left side of her face was swollen. She seems to be exciting. This morning, she became like this photo. The left side of her face has a big blue jelly. I feel that something like a protrusion can be seen through the jelly. Too much excitement? Did the organs of the body come out? What should I do!?
