Tons of Little Snails
Every night when I turn my lights off I see within an hour about fifty little snails on my glass. I have a friend with a tank that has been up a lot longer than mine and he has the same thing, but with one difference - mine are a zillion times larger.
My friend's snails are just big enough that if you put your nose to the glass you can tell that they are snails. Mine are approaching half an inch in size. I have astreas in my tank (which these seem to resemble some.) Did one of them multiply, or do you think these things popped out of my sand/rock and they won't get any bigger?
