#margaritasnail

Hey! Little new here! I have a Margarita snail with a white thing growing on them(can see in picture). I tried to do some research to figure out what it is but I’m not sure. Was curious if anyone else has scene this and knows what it is. If so please share the any info you have! Thank you!

Just recently saw a new baby snail in my tank! Can anyone identify it?The only inverts that I have in my tank that I know of are... margarita snails, narssisus snails, stomatella snails, and conchs.
