platygyra growth

[Housegroove76]

I think this is a platygyra, it's been awhile since I bought it. Anyways, I just noticed these white squiggly lines coming off it and were wondering what they are.

Is this the begining stages of it growing? I touched the lines and they are hard so it's not organic as far as I can tell.

Any help would be appreciated.

Hi , pics under white light will help, look like calcium based tube worms from what I can see...

Here are some new pics under white light. I noticed some new ones not by the coral.

+1 tube worms or feather dusters

Platygyra doesn't exhibit any kind of 'white' growth areas. It just slowly gets bigger. One day, it's the size of a grape. A few months later you'll pass by the tank and realize, wow, it's now the size of plum.
