Brown spots on LPS corals?

[user17482]

Hi, I have just noticed these brown spots over several of my LPS corals! I am wondering if I should be concerned about this? Other than this I have seen great growth and polyp extension from all the corals specifically from the octo spawn which has had its sweeper tentacles out most days. ( keep in mind all the corals are closed up right now ) I do have a cleaner shrimp the sometimes irritates the corals. If you have any tips or information please let me know! Thank you :)

The first pic definitely looks like flatworms!

While it's hard to tell, they don't look like polyclads (euphyllia eating flatworms), but you'll still want to get them off the coral flesh asap.

Yikes, euphyllia eating flatworms. Take it out and give it an iodine/ReVive dip, make sure to shake all of the flatworms off in the dip, repeat this process every other week for about 2 months, this is to kill off the eggs. Also Halichoeres wrasses will eat them (@i cant think?) though in this situation it's important to kill them.
