Found this on my Tiger conch

[cytotoxic]

I got a new tiger conch yesterday and added it to my tank. It seems to come with a hitchhiker near the rear spiral, any clue what this is? And should I remove this?
It seems to have trunk just like a conch

Images under white light might help to get a better look. Chances are it's harmless, but taking something out that you are not sure about is the safest approach.

You could take it out, put it in a small container, and then you will be able to get a better pic as well as be able to keep it from harming anypne (if it's dangerous)
