Flatworm ID?

[nuvocube]

Can anyone ID these flatworms? I know some species are harmless to coral. They appear brownish under white light but translucent in the tank and have a split tail. I’ve only found them on the glass hanging out with the copepods so far and haven’t seen any on the coral. I’ve been siphoning them out with a pipette whenever I spot one.

Some Acoel, possibly Heterochaerus sp. or Amphiscolops sp. (may as well be some other genus, but those are the more common ones in reef tanks I'm aware of)

Usually harmless, just ugly. As long as they stay off your coral polyps, you should be fine. Many eat copepods though, which is a bit annoying but not the end of the world.

Would you recommend a wrasse or just leave it alone? I’m skeptical putting any un quarantined fish in my system and do not have a qt set up.
