Essa eu nunca tinha visto, fui dar uma geral hoje no reef, namorar um pouco, recolocar alguns corais que insistem em cair (por conta dos paguros alpinistas do Matias).
Deparei com a colonia de Dunca (Duncanopsamia axifuga) com 5 ou 6 bocas totalmente mortas, umas 4 bocas bem e acho que umas 2 com um meleca marrom em volta e por dentro.
Fiz da mesma forma que usei em outra ocasião em uma frogspawn, descolei a colonia, coloquei na frente da circulação bem forte (para remover restos de tecido) e recolei em outro ponto do aquário, pelo menos 3 bocas se mostram saudáveis, espero que se recupere, tenho esse coral já tem bastante tempo.
Não tirei fotos, porque na hora que vi, já descolei e comecei a limpar, mas amanha tiro fotos do que sobrou da colonia.
Agora, em Dunca, eu nunca tinha visto, dei uma pesquisada rápida, e vi um post na reefcentral de algo parecido.

Eu tenho uma muda dessa dunca aqui tb. Verdade esses dias vi dois relatos estranhos de brown jelly, um em Plate long tentacle e outro em dunca mesmo. Normalmente aparece em euphylias.
Renato... Você chegou á ler alguma coisa sobre "A causa e a Cura" ?
Perdi mais de 10 bocas de torchs em menos de 2 semanas, e já dei banho com Reef DIP, Coral Restore e nada adianta, as bocas que restaram parecem estar saudáveis, e quando menos se espera, no dia segunte está mortinha e com resquícios de tecido ainda com a maldita Brown Jelly em cima....
Que raiva do caramba... Vou dar uma pesquisada, mas hoje em dia o tempo está curto até mesmo pra frequentar o fórum.. :(
"Copiar uma idéia é plágio, várias idéias é pesquisa"
Brown jelly disease, as it is sometimes called, is a very serious matter and, if not dealt with immediately will result in progressively more and more loss of tissue and eventually the loss of your coral.
One method we can implement to minimize damage to corals is to ensure that all of them receive good water current flow over their bodies (polyps) and that the flow is uneven. Laminar current is not really what you want.
Irregular water motion is better and cleans the coral better. This often prevents bacterial infections and the ensuing bacterial disease and the associated degradation of the coral from even starting.
Let us look though, to begin with, at what other causes start these infections and what happens when the disease sets in. Additionally, let us look at what we need to do when bacterial disease occurs and what we can do to prevent it from happening (at least for the greater part, as avoiding it completely is not always possible, however much we would like it to be so). Let us look too at what we can do to arrest it. Potential Causes
Corals are in an environment of real low water quality parameters:
High levels of total nitrate are often an indication that the water quality is low and may lead to the start of bacterial disease. Total nitrate is calculated by taking the nitrogen-nitrate reading your test gave you, and multiplying that number by 4.4. Note that most tests on the market give results in N-NO3 and not in "total" nitrate. Normally the instructions that come with the test will say so. Some do not. If you are unsure about what your test really measures, you can always resort to calling the manufacturer. When your N-NO3 level is high, e.g. between 60 and 80 ppm, your real nitrate level (total nitrate) is really between 260 and 350 ppm. This is extremely high, and sure to endanger your corals and your fish as well. Fish suffer from high nitrate levels in the tank too. There is another document on our Web site that deals with this in more detail. High phosphate levels may contribute to this too, as they will result in wild, and sometimes totally unexpected, growths of undesirable micro-algae. These can, and often do, grow on the corals skeleton(s) and may start affecting the polyp too if the growth continues. Remember that some algae give off toxins (releasing them on the coral polyp if that is where the algae growth is occuring). High silicate and silicic acid levels (ppm) give rise to the appearance of diatoms (hobbyists refer to them as brown algae). This can affect the corals too and often does (see below). The real danger lurks when encrusting diatoms start to grow on the skeleton of the coral, start moving upwards along the skeleton, reach the polyp, and start pushing the polyp out of the way. When this happens, the polyp detaches from the exoskeleton and loose fringes of polyp are/may become visible. Sometimes these polyps die off and holes or bare patches on the skeleton (missing tentacles of the polyp) are clear evidence that this is what is going on.
Other Potential Causes
Besides the water quality deterioration or bad condition of it, there are other other causes that can lead to the onset of bacterial infections. The main ones are related to damage that occurred to a coral, the damaged area gets infected and bacterial disease follows.
Here are some of the reasons:
An urchin, while crawling through the tank, inflicts a scar or puncture to a coral Sweeper tentacles from other nearby corals can sting a coral and leave a puncture of damaged area behind. A piece of rock falls on a coral and causes a puncture or damage. Bristle worms gnaw at a coral and cause damage. A mantis shrimp with its razor sharp front mandibules causes damage when it touches a coral or brushes it while roaming around the aquarium A fish causes damage in the process of touching a coral, possibly through sharp gill end, or in the case of Tangs, the brushing of their back razor sharp protective modified partial fin against the coral. Any fish that eats polyps damages a coral (e.g. Angel and Butterfly fish - I include Pygmy Angels in this category by the way as some will harass corals and may damage them in the process). Hermit Crabs can cause damage. Small algae eating crabs can do the same, inadvertently but with the same end result. Stone crabs moving around and touching corals or rubbing their claws against them, even if not on purpose. Some shrimp may do the same, even inadvertenly. Some nudibranchs (most are carnivorous) feed on corals or leave toxic excretions behind. Detritus that accumulates on corals, rots and is not removed by current will eventually damage the polyp of a coral to the point where the damaged part can easily become infected. Some sea slugs Wrasse that are not reef compatible present in the aquarium. In this respect it is very important for hobbyists to ensure that whatever they add to their tank, is compatible with what is already in the aquarium. This applies to any type of animal you add not just corals and fishes. Some snails that get onto the coral leave toxins behind as they crawl along. These toxins may harm the polyp. The secretions left on the polyp may, in fact, harm the coral and cause damage. Small worms that attach to corals (usually white and round type worms). They are hard to eradicate and multiply rapidly. Another document will be added to the Main Library to deal with the eradication of these worms. In brief though, irritants have to be used so they detach and can be siphoned out. Some fish eat them. Six-Line wrasse are a good fish to try out. Algae that touch corals can, while excreting toxins and general excretions, damage a coral. and so on. This is a pretty good overview and you should have gotten the picture from this list how easily, indeed, damage to a coral can occur. Remember that "any" damage can develop into bacterial disease.
As you can see from the above, damage to corals can be inflicted by many animals, even several we do not suspect of causing it. Lesions, punctures, sores, and so on, can all result in or to progress to bacterial infections! A lot of the reasons for this are not known, although water quality is certainly one of them (in the true sense it is the lack of good water quality that causes it as this condition is conducive to many bacteria and microbes being present in the water. Good water current directed at a coral can keep such from getting a hold and developing into a full-fledged infection, but no guarantees can be offered in this respect.
At times, regardless of what you do, and how well you manage the life forms in your tank for compatibility, damage to corals may occur and bacterial infections may break out. What to do when a bacterial infection is present? Below are some suggested techniques you can use. You can use only one of them, or several, or any combination of them:
As indicated previously, make sure that the water currents in your aquarium that go by and over corals are strong. Most corals do need this type of current. Good examples are Bubble coral, Goniopora, Elegance coral, Frogspawn and other Euphyllia corals. Do everything that you can to maintain very low nitrate, phosphate and silicate levels. Use chemical filtration compounds to achieve these low levels if you need to. Several articles in the main library deal with algae and how to control them. You may wish to read and download them. Test your aquarium water and the water you add to the tank regularly to ensure that none of these levels get out of hand. You can check the water quality parameter article for more details on what these levels should be, in greater detail than given below:
Nitrates between 5 and 10 ppm total nitrate. Note the word "total". It is very important in this context. Phosphates between 0.02 and 0.04 ppm. If they get any higher micro-algae will start to appear. Silicates below 0.5 ppm. Anything higher than that level will cause diatoms to grow. Some of these may attach to coral skeletons and cause damage, as explained earlier in this article (the real dangerous ones are the encrusting types of diatoms).
When a coral is infected you can try the following method:
Remove the brown slime stringy material (you can often siphon most of it out). Do this while the coral is still in the aquarium. Hold the siphon an inch or so away from the slime and start the siphon. Dump whatever you siphon out into a bucket. Do not reuse the water in that bucket. It is laden with elements and chemicals you do not want back in your tank, besides the slime that you removed and that you do not want in the tank either. Note that sometimes you need to siphon this off several times, hours apart or on consecutive days. Slime may reappear and needs to be removed. Dip the affected area in water for about 3 to 4 minutes. You need to use saltwater and add iodine to the water to kill off the bacterial disease. How much iodine you add depends on the strength of the product you use. Some brands are 2 % solutions, others are 5 % and others yet are much stronger, 10 %. Of course Lugol's is even stronger and can be used as well. 10 to 20 drops of a 5 % solution to a 3 gallon bucket is what is usually recommended but it is best to check with someone in the know. Note that overdosing on iodine can be a reason for bleaching (personal comm. Bruce Carlson) and only increases the problem. Dose the water correctly. The best is to start with 10 drops of a 10 percent solution and repeat the bath a few times over a period of several hours. This will usually take care of the problem. Another method is the use of chloramphenicol (if you can get it as it requires you to have an MD prescription. This method is the one suggested by Dr. Bingman. Note that a more detailed article on bacterial disease will be added to the NetClub™ library. Vitamin C treatment (as described below) is recommended as well. Read the articles on Vitamin C on our web site to find out how to use this method and how to dose. Clean the affected area with a real soft brush wiping any brownish material you see off the coral. Rub some powdered Vitamin C on the affected area. Hold the coral out of the water for a minute or two to let the C work its way into the wound or sore. Treat the entire tank with Vitamin C at the therapeutic dosages recommend in the Vitamin C documents in the TT Web site Library. Both gives complete details on how to use vitamin C and what kind you need. See below for a link to the Libray. Keep treating the tank with vitamin C for at least 14 days. This is most important if you want to achieve the results you need to achieve: healing of the coral and eventual regrowth of the polyp in most cases. Aim good and strong water current at the coral's affected area so it does not become reinfected. There are no guarantees but, the use of Vitamin C will, in the majority of cases, prevent reinfection based on my long time experience with using C in high dosages.
Of course, in addition to all of the above make sure that you improve the water quality in your tank. This is one of the most important matters to take care of, second only to the use of Vitamin C.

This is a coral disease that is almost exclusively found in aquariums. As its name suggests, this disease appears as a brown, jelly-like substance on the suffer of the coral. It's also described as a light-brown colored slim or ooze "floating" above or around the coral. The jelly is thought to be a mix of dying coral tissue, bacteria, Protozoans and possibly other things. The specific culprit is unknown. With so many different microbes present in the slime, it's hard to say which is "causing" the infection and which are just opportunists feeding on the already dying tissue. In any case, it is almost always caused by a physical injury to the coral. It moves quickly and can kill a coral with in a few days or weeks. Simply put, brown jelly disease for a coral is analogous to a badly infected wound in any other animal.
If the disease has just started and the infection is small, the best treatment is high water flow and at least daily cleaning of the infected area (usually done with a turkey baster). If the disease is severe, the infected part of the coral may need to be cut ("fragged") off of the colony. The choice to quarantine is up to you, but brown jelly is not usually contagious (unless you have other injured corals in the tank). If your other corals are healthy, they will likely resist infection even in the presence of an infected coral.

após algumas leituras penso que contusão, guerra química, corais encostando e stress por água não apropriada são causas.

Pesquisei um pouco sobre o tema, não só nesse link e achei o seguinte:
"Nitrates can be very harmful for the aquatic life within your tank. Many marine plants and algae feed on nitrates. So, nitrates are the leading cause of an algae bloom within any aquarium. Although less toxic that Ammonia and nitrites, nitrates can lead to stress. This is because increase nitrate levels make the fishs internal organs work harder. Stress causes disease and death. High levels of nitrates adversely affect the health of the fish living inside the tank. High nitrate levels are generally the direct result of poor tank and water maintenance."
Fala que pode gerar stress e o organismo do peixe acelerar causando a morte. Discordo, qualquer coisa pode estressar o peixe e causar a morte. Teoria furada e sem fundamento.
