What’s wrong with my nassarius snail?

[hannernanner]

I added a few snails to my tank yesterday (they are my first inhabitants) and this nassarius snail appears to have something extra sticking out of its shell? You can see in the photo. Is it stressed? This one has also been on the rock work all day which is weird because I thought they like to be buried in the sand. Am I worrying over nothing..?

Are you referring to the single siphon/probiscus?

 

[Saltyreef]

The nassarius has a tube that protrudes from its frontal section.
Youll see these tubes sticking out of the sand when they bury themselves in the sand.

No I definitely know what the siphon is, but if you look closely there’s a second tube-looking think coming out

Hard go see in pic. They also have an appendage as part of their foot. Think you are referring to that which is normal.

See photo.
