Weird white film with "branching" structure?

Posted weeks ago with 0 response, trying again. Anyone know what this white film below the flesh of my acan is? Appears to have branch-like structure below the surface?

They have been on this coral and only this coral since it was in my old tank nearly 2 months ago now, it was dipped in iodine before adding to new tank. If it was dinos, would they have died in the dip?

Sponge, possibly mixed with hydroids and or feather dusters.
The Micromussa looks unbothered.

If it is sponge, thats nice to hear. There is no negative to sponges that I know of?

No. However if it were my piece I would remove piece, place in a separate container and take a soft tooth brush to the piece.

Just for the potential health if the coral or the tank as a whole?

Just the Micromussa, and only because of possible hydroids. It's a great frag.
