Help: dying corals

[whatcaneyedo]

I've encountered brown jelly infections in four different situations. If water quality is poor and a coral is physically damaged it can form. If a coral is being attacked by another's sweeper tentacles it can form. If a relatively large piece of food falls on a coral and is not consumed but instead sits and rots it can form. Finally, if brown jelly from an infected coral separates and lands on a healthy coral it can spread to it too.
