Purple polyps

[Madreefer]

Rather than wasting your time researching them try to find some fluke tabs. I know exactly where those clove polyps came from. In case you forgot i babysat your rocks for well over a year before they went in your tank. And i never dosed those rocks cause they werent mine and covered in hair algae and hydroids. I see in your pics that they are now growing on your hair algae. You will have to double up on the dosage too before it kills them and you'll lose your shrimp too if you don't take them out. They are not at all like the polyps in Kiens tank, they are extremely evasive and ugly and I just about got to the point of shutting my tank down. If you don't tackle them now you most likely will not be able to keep zoas or most SPS as they get out of control.
