I wouldn't worry too much, suspect that in a day or two thing will calm down.
As for the skunks and the O's, everyone seems to say that they are peaceful. IME, that changes very quickly when they start to spawn. Awhile ago I introduced a small Potter's angel to my tank, which had an existing Potter's. The existing Potter's didn't care at all, but the pink skunks on the other hand, chased/nipped at it for the first week --- all over the tank. After that they got better, but if the new guy even came close to their anemone, (( and the eggs )) they would go after them again.
