Pest on Goni? ID please

[adamlodge14]

Hiya guys,
I picked up a green lash goniopora yesterday, but today I have noticed these black hair like things at the bottom near the frag plug, is this a pest?
I dipped and acclimated the coral properly.
(The Goni is still closed because it’s first thing in the morning)
