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)

Hoof snail - neat and harmless:

Yeah, looks like either a Slipper Limpet (genus Crepidula) or a Hoof Snail (taxonomic family Hipponicidae) - both are harmless; slipper snails are filter feeders, and hoof snails feed by extending a long proboscis (think like an elephant's trunk) to eat either their host snail's waste or any food it can reach from its host's back.

Yup, I googled this and it is in fact a hoof snail. Someone also posted a video on Facebook of a tiger conch with another snail attached, and the one on my conch is almost identical, with its feeding proboscis. Also saw a post on R2R with the same scenario.
Thanks for calling out its harmless, I’ll simply leave it alone
