Looks like a stomatella snail to me.  Does it have a part shell on it.  Kind of the shape of a fingernail.  If it is, they are good.  We have at least 5 in our tank.  And every once in awhile they will puff something which I think is eggs because the fish will hurry and eat them.  And when one puffs, you can see others puffing at the same time.  You don't see them very often in the daytime, but if you peek in with a flashlight  in the early morning, you will see them out on the rock.  Google them to make sure this is what you have.
