Some pictures...there seems like 4 different types here - green, red, wiry, and branch.  Also, in the last photo, theres something with green tipped tentacles.  I've been watching this for a while, seems there are about 4 heads, they retract when touched, but not into rock, just into a polyp.  
 
Based on NU-2reef, best option is to blast with boiling water?  There's another active thread on this method so I will read up on it.
 
I forgot to mention, I have 2 54w T5H0 fixture, I changed the white bulb last month, was told the blue was fine for another few months.  (supplement lighting with LEDs)
 
Thank you for the help.
