I have a new THING in my tank !?! The other day a worm looking thing blocked one of the nassarius snails from being able to move around one of the rocks I have no idea what it is and need some help!!! It seems to be in a rock or sand and we have noticed a casing that shows up on a rock evey few days, and my little bristle worms have disappeared as well that lived in the same rock !

It resembles a Nemertea Worm. They prey on anything in the sand bed including Snails. It looks like the Nassarius Snail was too much for it to handle at this time. Once it grows up some more this Snail will be on the menu.
