I’ve heard that white flatworms are usually the Acro-eating ones. Anyone who knows the differences between the flatworms can chime in to confirm?
My my 4 wrasses don’t see interest in it, and it seems a bit larger than other flatworms I’ve seen in past.
There are many species of flatworms. With that being said in my experience any of the large white spotted ones are not good for tanks. EEFW and AEFW have that same general coloration and look. I would def remove and inspect your coral.
