Well, I cut it from the rock and moved it to another piece that I have in the sand bed that is isolated from the main rock. I will keep an eye on it, if it starts to get crazy, I will remove it. I hate to kill it because I like the color, but I do not want it to crowd my rock work as I do plan on adding more LPS and Soft corals. Thank you again for the honest advise and opinions. I researched both anthelia and sympodium and it is rather difficult to conclude on which species it actually is because there are similarities with both, but I am leaning towards anthelia. I went back to my log book and It was so strange that it just came out of no where, I cycled the rock in some buckets with no light, then cycled the tank with the rock and no light, added biospira (I was curious), waited on the chemistry to stabilize, added a few chromis', then I started adding corals, but it wasn't until I began dosing limewater in the ATO that the mystery soft coral began to creep out of the hole in the rock. It could have been just a coincidence or maybe the pH was too low for it to recover and the limewater raised it enough to kick it into overdrive.
