Little curley Q looking white things on your rock? If so its nothing to fear, they will soon encrust your back glass and appear hear and there if your calcium is maintained correctly.

Don't see an image here but could be fungal, maybe bad, but is probably tunicate sponge or small feather duster which are both good. If ya post an image someone will probably know for sure.
