I often have people come in the store with dying corals claiming they are sufferiung from brown jelly diease.....when the "brown jelly" is simply the rotting tissues of the coral due to unkowns.I would take an affected piece out and smell it. The results of this test are obvious unless you have no sense of smell.....brown jelly smells a bit (also is unpredictable)....or if the branch or portion your smelling makes your stomach turn it is dead, decaying and unsalvagable. BUT....the death of many corals results in the decay of tissues witch turns to a brown stringy goo so..... whatever the state I would treat afected portions of the corals as malignant tumors and perform surgery as suggested by others here. I've run across many inkown ailments in many corals at my job and fragging out the "diseased" portions works most of the time. If the diseased portion ids in the center of a lrage coral and cannot really be fragged of i have used gel super glue and "sealed" the aflliction in place.
