I have this newer addition to my reef tank. It appears to have some white/creame areas that are showing up on it's fins and forehead. The spot on it's forhead showed up about 3 days ago, and actually seemed to protrude from the skin. It has since subsided and seems to be less pronounced today. There are other areas that have that have similar symptons...yet the forhead is the only area where it seems to protrude. The rear fin seems to have the most spots. There are also a few areas on the side of the fish. They're not the easiest thing to see, and I appologize for the mediocre pics. I thought maybe it's brooklynella, but was not sure. Should I be worried about this spreading to other fish? Is it a serious condition requiring QT or will a vitamin and garlic soaked diet be sufficient? Thanks!!
