Favia

[Temp]

Can anyone tell me what the lighter purple stuff is on this favia? Is that growth or would it possibly be skeleton?

The outer rim is showing some skeleton.

I'm assuming it's a new frag to your tank.

Yes it is. When I first got it, the green was only a circle in the bottom of both heads. Not sure if it's growth or if it's dying.

Looks like it's growing to me ;)
