I noticed this after putting my live rock in my new tank when I first noticed it was standing up Luke 3/4 of a inch tall and discharges waste or somthing. Here's a pic I've seen 2 of these so far.

very good for you tank and a great addition to the clean up crew.
Ive been told its a good sign your tank is maturing.

The discharge was it trying to spawn. They control their own numbers and will never get out of hand.
youtube 'stmatella snail' and have a look

(please correct me if i'm wrong. This is just what I've read)
