This looks to be some sort of limpet, was on one of my trochus snails. Ok to let it into my system?

Thanks!

Looks like a limpet to me. Does it have a little hole on the top?

Doesn't seem to have a hole on top it's way more conical than that image.

That picture isn't the best example. Keyhole limpets are pretty common hitchikers.

Funny you just posted this as I was about to ask a similar question with 2 things attached to a spiny astrea snail:

What is attached to the other snail is a slipper limpet.
