I don't know if I'm not observant or if my snails are sneaky. It seems like my snails grow when I'm not around watching them and even though I check them out daily when feeding them, it seems like - Poof! They grew! It's not like they get a little bigger, it's more like all of a sudden they are alot bigger! Anyone else ever have that feeling? With my fish I can usually tell but not when it comes to the snails.
