Help Request - Unknown Hitchhiker

[saltwater-virgin]

I'm new to the hobby and have been learning lots from this site ... thanks to all who have posted the great info.

I have a question and I hope this is the right place to post.

Any ideas on what the white creature is in the picture? It is about the size of a dime. Came on a piece of LR I picked up at Big Als earlier this week.

Could be a leather. Its hard to tell from its size.

Looks like a Mojano anemone.

Definitely a Mojano. I'd get rid of it ASAP before it spreads.
