Can anyone tell me what these are? Having a hard time pinpointing it on google. These started to emerge after a large die out of yellow polyp rock I had. The rock was covered with 30-40 yellow polyps heads and died our big time for unknown reasons all water paramiters were good. Theres a few yellows still left on the peice of rock, maybe 3 or 4 but now all the purple guys are multiplying and starting to cover the rock. Any ideas?
