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.

I think you're right. The more I look at the two the more they seem to look different to me. I didn't think that there was a difference between blue cloves and purple cloves but there does appear to be a difference. At any rate, when in doubt, NUKE IT!

Yea these one are not nice. The pic has captured the color right. They're a brownish purple color and they grow that matting like green star polyps have. When you do scrub them with a brush a purplish cloud comes off of them. I've scraped them with a knife, used a brush, kalk paste etc... Nothing works but fluke tabs. I beleive Aquattro fought the same polyps and that's all that worked for him as well. Rock is cheaper than future coral purchases Dearth, it might be just as easy to start with new stuff. Trust me on this one.

I had 3 rocks with the purple clove polyps all 3 were given a fresh water bath today killed all visible infestation so we shall see if it makes another appearance
