i guess i'm also wondering if acropora eggs are stored in the skeleton like that...

It could possibly have been stn'ing because it couldn't get enough nourishment to make the metabolically expensive eggs and keep growing at the same time.
Received a call from a friend, who described what looked like red burrowing worms INSIDE a Blue Tort. I had to see that, so I ran over took some pix. It looks like the worms borrow in and tunnels through coral.
Mild case of basal STN prompted further investigation, which led to the discovering. The coral was in his system for a least 12 months.
Red Worm infection.

A couple of pictures from the outside, once broken open they looked like the worms in the OP's post but I cant find those images at the moment.

In the second picture the calcium carbonate has been dug away to expose the worm flesh.
I cant see these being egg or sperm ducts in this case as the corals strip up to the point the worms terminate. I think they devour the flesh at the tip of the worm from within and slowly move up the coral. The ones that are just visible under the fresh stripped base look very much like varicose vein threads. Unless this is something different than the OP's but it was worm like, red looking when broken open ,within the skeleton and killing corals.
