White worm? on Hammer Coral head

[rustic_reefer]

Noticed a head of my hammer coral was irritated and not fully extending. Upon inspection found this white tangled stuff. Trying to determine if this is a worm irritating my hammer coral or if it is just discharge - and if I should just remove the head. Thanks in advance for any advice.

Not a worm. Mesenterial filaments. Guts of the coral. Usually not a good sign.

Is it just the picture or is the head deteriorating lots of skeleton around it

It has deteriorated, but it has been about the same for about 4-6 weeks now.
