Hi! I just bought an astrea snail and found a snail on it. I took it off the shell of the astrea and flipped it over. I have a Stomatella in my tank and it looks similar by the shell, but the problem is, I flip it over and it looks like a snail inside a too big shell. Here is a picture because videos can’t post. He is very active and I’m surprised he is still alive because I left him there basically over night.
