Help ID this flatworm in my reef tank

[amarti2038]

Hi everyone,
I just found this small flatworm in my reef tank and I’m not sure if it’s harmless or something I should worry about. It’s rounded on one end and has a small notch on the other side. I’ve attached a photo for reference.

Any help identifying it would be really appreciated!

Thanks in advance!

In general, its some acoel flatworm, probably looking for a food source that may not be present in the tank, which is sad for the worm but good for the reefer since you are not posting an image of a shrinking, dying coral with a worm sucking the juices out of it.

Otherwise, i got nothing for a real id on this one.

@ISpeakForTheSeas -?

I'm late, but Acoel flatworm is as good of an ID as I could give at the moment - I need to learn more about the various Acoel taxonomic divisions, but I don't have time to do that a the moment. Generally speaking, Acoel flatworms are not as harmful as others, and I would assume this one will die off shortly, but I can't rule out it reproducing enough to become a problem.
