Micromussa/acan help please

[Thingsibuild]

I picked a single head frag of a rainbow variety, on the way home the skeleton pushed thru and now it's got a brown mucus looking stuff stuck to that area. It's just on the small exposed area. I did a iodine dip. but it came back and I'm feeding it well.
Should I try anything else?

Is it looking good now? I've found that a lot of micromussa, acanthastrea, euphyillia when they shrink up a lot it looks like the skeleton is coming through but they just have such thing skin being pulled so close it appears that way but they are fine.

If it looks good now and is eating then I wouldn't worry.

Its puffy in area around the tear and the it does open up to eat. I'm worried it's going to get worst. Its been three days and it's not changed much.
