Dark spot on dunkan moving!!!!

[olonmv]

has anyone ever noticed dark spots on a dunkan coral move? I noticed a dark spot on skin of my dunkan yesterday and it’s moved. Is this normal? I’ve also noticed an explosion of head growth in the last month. The spot was literally where the arrow is pointing this morning.

Very hard to tell what it is under blues. Could possibly be a flatworm or something. Duncans are hardy though and if growth is good I wouldn't worry too much.

Here’s a shot with just whites on. Almost normal but with lights back on blues it’s dark. And for sure it’s moved and I’ve noticed another.

Could it be a new head looking for a place to sprout?
