Can't decide what this is???

Hey, hope you all are having a good day.

I have a lot of these on the front glass of my quarantine frag tank. They showed up right after I received three shipments of corals from 3 separate vendors. I am glad they are in quarantine!

I feel like they are a type of flatworm.

Thanks

You're correct. They are flatworms.

Flat worms, usually aren't harmful unless they're smothering corals. Yellow coris wrasses do very well at pest control.

Yay. I was just on your guide, is it the Acoel??

That is what I am hoping. My first thought was a coris wrasse, but I need a little sand to put in a tub in the tank... and then I probably should have a screen top...

Yes, that's an acoel.
