I too, have blue clove polyps completely taking over my reef. They have killed off most of my zoo's, I try to brush them off with an old toothbrush so the zoos can get light, only to have them return with vengeance. They are growing and covering all kinds of things, the "stems" on my candy cane, almost covering my beloved palys, even in my sump with a 40W CF, only on 16 hours.
I studied reef tanks for 5 or so years before I started, and broke one of the cardinal rules of knowing everything about a specific coral species before introducing it to my tank, typical stupid me. (although, in my defence, they were not on the radar like gsp or xenia)
If anyone has any available fluke tabs, or would know where I may acquire some, I would be VERY willing to take a few off your hands. My tank is 17 gallon display, 20 gallon sump. I think I may try posting in the wanted section, I am very unfamiliar with the whole posting thing, sorry.
