Duncan coral assistance

[fsas89]

Just got this Duncan 3 days ago and I just noticed these yellow spots and tube. Any suggestions? Also that back left polyp hasn’t been opening, related? Thanks In advance !

Looks like a vermetid snail to me. Just break it off...they are annoying and I don't think you can really avoid them but they aren't going to kill anything.

Vermetid snails.

As for the back polyp opening...might have been annoyed by a vermitid web, or maybe just moody. One or two of my heads occasionally retreat for up to a few days at a time....
