STN/RTN or Bite Marks??

That doesn’t look like a normal STN pattern to me. My money is on bite marks. Have you tried hitting the corals with a turkey baster or power head to see if any flatworms blow off?

1st pic looks like convincing evidence of AEFW bite marks, towards base. They love smooth skin acros, that one is a beauty Jorge!!!
DBurr advice excellent to detect. Several ways to deal with them, so don't have any knee-jerk reactions, do some research and manage them while still enjoying the hobby, which is very possible

thats when you become a true reefer. you learn to handle the pests! Natural flat worm eaters, peppermint shrimp eat the eggs and some of the flatworms, 6 line wrasse eat the flatworms too. good luck.

Yea wrasses and shrimp might be difficult, since i have a mystery wrasse that doesn’t play nice and obliterates shrimp.

They do not appear to have encrusted on to the rock. That’s good, you will have an easier time dipping them.
