not sure ,ghost ??
 
ghost flatworm , doesn't look like polyclad
 
Yes, flatworm, but not the kind that are immediately an issue.

These eat algae and copepods, not coral. They can become problematic if their numbers increase to the point that they smother coral from getting light, but I've personally never seen an infestation even close to that.

They can also release toxins when they die; if a bunch die at once (like when using Flatworm Exit, etc), the resulting toxins can be bad for the tank... People usually remove as many as they can manually before using FW exit, are prepared to do water changes, and run carbon to mitigate the toxins.

Lots of fish will eat them including most wrasses...

If they are crawling all over the zoas, that could be irritating them...
