Unresolved Some sort of flatworm?

Have you bought any new corals lately ? Like xenia, toad stool .

Does it have a shell I can not tell for sure?

 

My most recent is the St. Thomas. I have a toadstool also but I noticed these before it was introduced.

 

*Update*

New pic taken last night with flashlight. These things only come out at night.



As far as I can tell I have 3.They move fairly slow and haven't appeared to harm anything. They're also larger than the one pictured in my initial post.

 

These were tonight.

 

That's a chiton. Harmless.

Cheers,



Don
