Acoel or Ghost Flatworm?

[BReefer13]

Hey all. So I have had these flatworms for around 6 months now on my frag tank, they usually hang on the glass and (to me) look greyish. They also seem to hang on new frag plugs, while theyre still white. I have never seen one on any of my corals, even with flow turned off and carefully inspecting them.

From my own research I came to the conclusion that they are either Acoel or Ghost, but wanted to check on yalls opinion?

I managed to grab one under my microscope (300x):

Would flatworm exit be a good course of action here or should i just leave it alone( my frags continue to grow)?

Since it’s a frag tank and I’d assume no predators, I’d go ahead with FE because they most likely won’t decrease in numbers on their own.

I do have a six line and a coris wrasse in there. I wanted to initially properly identify ehat flatworm it is. Do you have any idea?

Looks similar to the ones in my frag tank. I've had them in every tank in various numbers since I started in the hobby a little over 4 years ago. I've tried identifying them and what I found out is that there are 443 (ish) species of "Acoel" flatworms, which isn't all that helpful. I've been unsuccessful in narrowing them down beyond that.

I tried Flatworm Exit once because the corals in that particular tank (softies) weren't thriving and I wanted to rule out the flat worms as a culprit. Despite being very careful I lost a blenny in the process but didn't eliminate the flatworms. I don't think they were the problem anyhow.

My current frag tank contains zoas/palys, a couple SPS, and assorted LPS. Everything is thriving despite the worms, so I just let them be. I have a six line wrasse in there but he doesn't seem to be earning his keep.

picture under microscope. 160x I think? The camera is 40x and the objective is 4x. I'm sorry for the poor quality, I'm a newbie with the microscope.

It's ok with the Image and the video, yo are doing it good.
The focus is ok, some times taking videos is good to zoom in and out and adjust the focus, that way when the light is under the object you can "see the leers" on it
What's the model you have? (can I ask for photo, or link better Please?

Seems like we are talking ghost flatworm. Not always do wrasses consume them but typically Lunare or melanurus wrasse would eat them. Best first step especially if not large in number is to siphon them up. They are not coral killers, however if they grow in large numbers, can suffocate a given coral.
Other recourse would be Flatworm exit. If using this method, dose at 80% of recommended dosage.
