What is growing on my sps

[MR BACKHAND]

Picked up a green slimer frag and one of the branches had 6 of these coming out where a polyp would be.I cut off the branch and dug 4 of them out with a pair of sharp tweezers. Any idea what they are? It has 2 tentacles and that’s all I see . it does not crawl around just lives in the tubes of the coral.

Thanks

I thought it could be a vermetid snail but when I dosed phyto and zoo plankton no web appeared. They are meaty like a vermetid . I will pick out the last 2 and monitor it from there.
