Another one of my Mystery snails appears to by dying. Grr!!! This is two in the past couple months, and three since New Years. They were all in separate tanks. My other two in this tank are fine, and this is the tank with the babies. My ivory snail has been floating for a week now hanging out of the shell. It doesn't smell, and I "think" I see it move (even though it's feelers and whole body is hanging out). There is plenty of food in the tank, and the parameters are perfect (I do water changes every day because it's not filtered). Ugh! Well, I've put it into a QT jar to watch. We shall see what happens.
