Need help with Pest ID

[ProvidenceTidalReef]

Need help with this pest. I know there is aptasia, filter feeder (looks like coiled dog poop) but I'm not sure about the *clear* one looks like some sort of anomone. Or some sort of worm. Not sure it's on the side of the plug mostly clear. . Please help
