What is this white cotton of my digi?

Any ideas? I'm dipping the digi in iodine at the moment.

Looks like it is expelling mesenterial filaments. Montipora usually only do that when stressed somehow, such as when flow is too direct, etc.

dont touch it, put it in some medium flow with stable conditions and leave it, a couple of hours to days and it will be fine.

Yeah my digi's used to do this when pecked at by my angel. Now he's gone Ive never seen the cotten since.
