stringy things from acropora

Hi everyone I got these white stringy things comming out of my acropora all the polpys are open and this just strated yesterday why? what is it ? thx's all

 

Could be mesentarial filaments but without a picture, I can only guess.

 

what is that? yea my camera is broken thx's though

 

Any chance you have a cell phone that you can take a photo? It is tough to be exact with out "seein"

I had something that sounds similar and it was from being stung by another coral-anything close that may have done that?

If the polyps are out-it doesn't sound "to bad"

 

no camera at all sorry, na it's not close to anything I'll keep posted if it gets worse or something thx's
