In my freshwater tank I have nerite snails, mystery snails and one Japanese trapdoor snail. I acquired this Japanese trap door snail in December. About a week ago I started noticing these little baby snails. I know they are not mystery snails because no egg sacs have been laid. And they don’t look like nerites, so I was assuming they are Japanese trap door snails, because I understand that the female can store sperm and use it later. Which means she could’ve gotten knocked up before I bought her in December. but these babies are not looking elongated like a Japanese tracked or snail, so I’m wondering what they are and how they got here! Can anybody help me identify them? They have more mystery snail-like bodies as far as I can tell, but they have these weird brown speckles that do not appear to be in a pattern. They are too small for me to tell how many whorls they have at this point. There are only six or seven of them, which was also why I thought they came from the Japanese trap door snail. Although they are not all exactly the same size!
