Flatworm?

[Dipi]

Hello!

Is this a flatworm? Is it harmfull to my coral? I just added an acropora for the first time and I'm concerned it can be an AEFW. I don't think it came with the acropora because it is quite far from it. Thanks in advance!

That's probably a Waminoa species flatworm - they're relatively harmless, but in large enough numbers can cause damage by basically smothering corals.
