My Colonial Leather Coral

[Jinx]

This guy is a major survivor! He's an original occupant from when I rescued the tank however this I'm not sure if him dislodging from the rock and forming those nodules as seen in the pics is a good thing or bad thing. He's not loose, still firmly attached so that comforts me. So I'm asking is this how they sprout new coral nodes or is this a more concerning problem

Tank:
29 gal BioCube original lighting, skimmer, modified filter over rock rubble, and a secondary pump.

No other coral within his reach or their reach.
Hopefully I've provided enough information.

Here is a pic of a very stable upright cabbage colony. If its growing then I'm thrilled to death if its sickly I'm discounted yet again from getting a colony started
