Got some wizard zoas that look kind of odd. It's just a couple of heads that are looking off. The frag had small black dots that were on some of the bodies. Not sure what they were but knocked them off and dipped heavy to try and help these guys out. Anyone have any other reason they may look off. Most of the heads are happy except when the cleaner shrimp walks by and brushes against them. It's just a small group of them that had those black dots. If anyone knows what those were id be appreciative. They almost looked like small barnacles of some kind. They were hard and seemed to be attached to the flesh of the body. Thanks in advance
