They dont look like typical pods I see in the tank..... anyone??

I've had these in my tank for at least 4-5 months now. Some zoas are fine, others seem bothered by them, but not eaten. See the timelapse I posted below. Every kept saying they are pods but they clearly aren't.

Timelapse of Acoel flatworms irritating zoas

Zoas have been partially open for months. I set up a timelapse to see what was going on, because there were no visible irritants or pests. As you can see in the timelapse, the polyps seem to close up in response to flatworms crawling over them. I believe they are a type of acoel flatworm. There...
