Cup-like opening w/whitish eyelash-looking sweepers

Anybody know what this is on our frogspawn? The sweepers go in and out. Feather duster? Thanks!

Appears to be a barnacle.

Also, I dipped a new zoa colony that had nudibranch eggs in Coral Rx but could not get all the eggs off. Would the dip have killed the eggs? It’s been a while since I’ve dealt with that once before so I don’t quite remember. Thanks.

Thanks! We looked it up and the photos do look like this. Any thoughts on whether to just leave it be or not? I’ll see what info I can find online in the meantime. Much appreciated.

It won’t harm the frogspawn but could irritate it which could cause it to decline. You could try to glue over the opening.

Sounds similar to spionid worms..
