Three heads on my large frogspawn colony dead. There is some stringy material rising from the top and I am not sure if this could be brown jelly disease? I have not added any other Euphyllia in probably over six months. Additionally, nearly my entire colony of montipora spongodes has RTNed in the past week. I have some pictures below. Any help/advice would be appreciated!
You can see the green tip of the montipora in this image in the back. The entire colony below it has turned white in the past week.
