Yes.. i would not add to tank, unless completely safe, can the eggs visible under ×2 magnifierglass?Inspect and see if there is signs of coral damage or egg.
If there is, I personally would not add the coral no matter what. But if you cannot do that, at least remove the egg and have the coral in accessible place that u can dip it when needed. Also have the coral bit isolated at least if you see hatchlings you can quickly take it out and dip it.
Read about the reproductive cycle of the nudi so you can plan proactive dips appropriately...
