Need Help Identifying Hitchhiker On Conch

[Hoodb]

Hey everyone,

A new conch I got was climbing up the glass and I noticed a black thing coming out of what looks to be a small red snail shell and I also noticed a couple others. Does anyone know what it is? Is it a snail? Is it a bad hitchhiker?

I can't seem to upload my video to the post but added it to a link here that hopefully works. I did attach some photos

Thanks for any help!!

I believe I found my answer and it may be a horse hoof limpet.

I agree it's a limpet. I had one hitchhike in on a hermit crab but it grew so quickly I feared it would quickly become larger than the crab.
