Since mine haven´t shown any sign of brown goo, I guess Brown Jelly isnt the case then....(If Candy Canes dont show it in a different way that is?)
The Brown Jelly Disease kill the coral quite rapidly also if I have understand it correctly...and mine have been like this for over a week now.
I also exclude light issues since all other corals seems to do fine.
Something that I have noticed though, is that ALL my Candy Canes dont estract as much as they used to, the colour is darker and I dont see as many of their nightly feeding tentacles as used to do...
