This morning my mystery snail started to lay eggs at the top of the tank. She laid a few eggs (clutch the size of a marble) then stopped. She sat there on the side of the tank for a while. I noticed she had 3-4 eggs stuck under her shell where they come out. I carefully removed the eggs. She is now sitting on the bottom. I don't know if the eggs inside are stuck. Can anyone please tell me what when wrong? Is she ok? Is there anything I need to do?
