Again very close, might have to wait till it grows out a bit. I recently moved it since this frag is several months old and has hardly grown. Move to area higher in tank with a higher flow rate and more direct light.
The picture of one in Corals of the World Vol. 2 page 362 looks a lot like yours.
If I am right:
Borneman says "most will thrive with bright light and moderate current" He also says that this coral produces a "heavy and thick mucus layer that forms mucus nets"
Sprung says:
Lighting needs: 5-9
Water Flow: 5-9
Aggressiveness: 4
Hardiness: 6
Placement: Chart shows that the species can thrive high, medium or low in the tank.
that is a hydno, dead on. We have one large colony and several pups that have fallen off and started growing. They go through phases (like most LPS.. they are an LPS, right ? ) where they inflate full of water and then deflate and the flesh rests against the skeleton. Your picture is of the later phase. Ours is even encrusting similar to how yours is at the base.
