Generally peaceful, but will fight each other for territory. But what is so scary about these demure anabantoids? https://doi.org/10.1016/S0021-9975(03)00010-0, Go, J., & Whittington, R. (2006). Dwarf Gourami Iridovirus (DGIV) DGIV, or to some DGI, is currently incurable, 100% fatal, and can be spread to other tank inhabitants – dwarf gourami or otherwise. The study shows that twelve gourami samples which had varied PCR results were used in a nested PCR assay all came out strongly positive for the detection of a megalocitivirus gene (Rimmer et al., 2012). This disease affects all variants of the Dwarf Gouramis such as the sunset or neon variants. https://doi.org/10.3354/dao048163. As within the case of DGD, there aren’t any identified remedies. I have 1 dwarf gourami and ... Is this dwarf gourami iridovirus? This virus is also believed to infect other fish like Swordtails and Mollys, possibly some Cichlids. Iridovirus in Dwarf Gourami: This is a severe infection that can cause death. Dwarf gouramis tolerate fairly high temperatures. Iridovirus disease in two ornamental tropical freshwater fishes: African lampeye and dwarf gourami. A study on the transmission and virulence of Iridovirus in Australia’s Murray Cod shows that DGIV was transmitted from Dwarf Gouramis from Southeast Asia. If it seems to be suffering it may be worth considering euthanasia. However, they are prone to contracting Dwarf Gourami Iridovirus, or DGIV for short. There’s a reason why Gourami are one of the most popular freshwater aquarium fishes out there right now. Thanks for this. Upon necropsy of DGIV infected gourami species, it was found that their abdominal cavities were filled with hemorrhagic liquid and heavy lymphocystic infections (Paperna et al., 2001). https://doi.org/10.1016/j.aquaculture.2012.06.034, Sudthongkong, C., Miyata, M., & Miyazaki, T. (2002). More recently vets have identified a virus called the Dwarf gourami Iridovirus (DGIV) that seems to be causing real problems on East-Asian fish farms. I’ve chosen the three individual koi varieties that I want, and some goldfish to boot, too. Yes my tank was properly cycled before my fish were put in. The non-native introduction of Iridovirus in Australia is further proven by a study which explores the susceptibility of native Australian species to DGIV, which is synonymously named, “infectious spleen and kidney necrosis virus” (ISKNV). Enhancing water quality in artificial environments such as UV sterilization may also provide some form of mitigation by killing off viral particles suspended in the water column. According to a study, “Diseased fish of African lampeye displayed pathological signs that were the same as those displayed in iridovirus infections of dwarf gouramis, orange chromide cichlid, brown spotted groupers and E. malabaricus, farmed in Singapore and Thailand.” (Sudthongkong et al., 2002). Iridovirus is a double stranded DNA virus of the Irdoviridae family. Currently most of the Trichogaster lalius are arriving in pet shops with a virus (Dwarf Gourami Iridovirus ) in them. It is possible that the bodies of infected dwarf gouramis were disposed of improperly into sewage systems that lead to the natural environment. After reading this I think he may has succumbed to this terrible disease. Knowing that it’s incurable is unsettling enough. However, despite the Dwarf Gourami’s demure size and attractive coloration, the species can fall ill with a viral disease known as “Dwarf Gourami Iridovirus” (DGIV). Are honey gourami different from the dwarf gourami? Yikes! which is a more pretty fish for a 29 gallon... http://www.myaquariumclub.com/dwarf-gourami-disease-17254317.html. So, how did this disease pop up in the first place? Conclusion. Please leave me a comment. Experimental exposure of lab fish to DGIV was also performed to examine the cross-infectivity abilities of the virus. The international trade of ornamental fish has aided the spread of these viruses to Europe and Australia” (Rimmer et al., 2017). I wonder if, I’m the future, genetic modification could be used to make the fish immune to this. (started with 8). The strong positive detection of the gene found in infected gouramis suggests that the dwarf gourami species are a major host vector or species reservoir. In conclusion, Dwarf Gourami Iridovirus (DGIV) is both a disease that greatly affects human society, it’s economy as well as a multitude of fish species. “A mortality event in dwarf gouramis imported to Australia from Singapore was consistent with such an infection and subsequently imported gourami have been detected with megalocitivirus infection.” (Go and Whittington, 2006). This study was performed by exposing multiple native Australian fish species such as Golden perch and southern pygmy perch to DGIV isolated from infected dwarf gouramis (Rimmer et al., 2017). a wiz member at My Aquarium Club. The homogenate was incubated at 55°C for 3 h Huh. Looks pretty scary. An investigation into Iridovirus in fish describes the virus as having icosahedral symmetry and measuring 130-300nm in diameter (Gibson-Kueh et al., 2003). From this information provided, it is clear that DGIV is easily capable of crossing the species barrier, which makes this viral infection very difficult to track down and isolate as it is transmissible on a global scale. Dwarf Gourami Iridovirus is a recently found among freshwater fish breeders. It seems like people still don’t know much about it, here is an informative thread from two years ago: I had a Flame Dwarf Gourami for a year, great health, always happy and wanting me to feed him, then one day I looked in and no little happy guy swimming around the glass :(. Dwarf gouramis tolerate fairly high temperatures. Nearly the exact same thing happened to me izzy3803. We’re talking about the Dwarf Gourami Iridovirus. Iridovirus infections in farm-reared tropical ornamental fish. It links to the short article I published years ago. A. So we’re literally getting crappy fish from the trade. Im really glad mine won’t die from this <3. “Outbreaks have occurred most frequently in East and Southeast Asia. So... what do you think? Dwarf Gourami Disease (DGD). Apparent occurences in Nepal and Myanmar are now thought to be as a result of misidentification. This was very informative. Lower quality fish can be much weaker and more frail, making it more difficult to regain its hardiness. (2001). Can... HELP! Iridovirus in Dwarf Gourami (DGIV) is an extremely infectious illness that within the majority of circumstances results in the loss of life of the fish. We’re talking about the Dwarf Gourami Iridovirus. Another investigation explored the mass mortality of Murray Cod due to being infected by DGIV. Some of the research and investigations that have focused on DGIV have found out that the disease is also capable of crossing the species barrier and infecting other species of fish such as other gourami species to food fish such as the Murray Cod. An outbreak of DGIV can cause high mortality rates, which then leads to a loss in revenue towards the aquarium or pet industry, affecting the economy. All my fish seemed sluggish and unhappy until I turned up my heat higher. Due to the weak immune and digestive system, this fish is affected by Iridovirus in Dwarf Gourami (DGIV). The the dwarf gourami disease only infects the dwarf gourami fish and has no known cure, but there are a few things you can do which I will go through below. The global exportation of ornamental aquarium fish such as the Dwarf Gourami and other species have led to the global transmission of DGIV, which then led to the infection of other naïve populations of fish through shared water sources. Temperatures of 80 °F (27 °C) are easily tolerated. Thank you. One latest examination of fish exported from Singapore discovered that 22 % of all dwarf gouramis carried the virus. Sadly my dwarf gourami Hannibal died from this a few months ago. Widely distributed through Pakistan, northern India and Bangladesh. I’m pretty happy with it! DGI is currently fatal, incurable and cannot be treated. Humanely euthanizing a few potentially ill individuals may also prevent any further spread of the disease to other fish, as it is probably better to humanely put them down rather than risk the chance of the disease spreading. He is barely hanging on. He was doing fine and then one day, he was lethargic, discolored, wouldn’t eat, and had sores all over his body. As both the main industries and native habitat of the Dwarf Gourami are in the same geographic area, it suggests that DGIV is a viral disease which originates in the same regions as well. I have 2 flame dwarf gourami 2 blue dwarf gourami and 2 swords in a 30 gall... How many neon tetras can live with a dwarf gourami in a 10 gallon tank? A research shows that around 22% of DG stock in Asian aquaculture centres carry this fatal disease. A., Tweedie, A., & Whittington, R. J. Furthermore, if the virus can still persist in corpses and enter the natural ecosystems, it could potentially cause an epizootic outbreak, and rapid extinction could follow. This disease has had a profound impact not only on the species itself but also on the aquaculture industry and society as a whole. Asides from the potential mass extinction event, aquarium industries are also at peril of losing income and revenue due to a massive die-off of infected aquarium fish. Go for a Honey Gourami instead if you want a small one. The Dwarf gourami, Colisa lalia, is a popular community fish that comes in a number of different color forms. The accidental or intentional release of infected fish, especially those infected with Iridovirus, can lead to mass extinction events of many fish species, in particular towards species with conservation statuses. This is so helpful and very well written!! Aquanick is It’s not the fish themselves that is scary, but it’s the disease that they may harbour that can be frightening. After reading this Blog, I feel very lucky that my gorgeous flame gourami doesn’t have this disease. A very good piece.

The family Iridoviridae, from which DGIV is a part of, is capable of causing mass mortality, disease and economic loss in the ornamental aquarium trade industry (Rimmer et al., 2012). Nutrition Aquaculture, 358–359, 155–163. Iridovirus disease in two ornamental tropical freshwater fishes: African lampeye and dwarf gourami. Nowadays all the fish on sale in the trade are mass-produced for the purpose and you’re very unlikely to encounter wild caught specimens on sale. And are dwarf gouramis ... Pearl gourami or honey gourami? So, ask a good nutritionist before planning a proper diet for this fish. Wow! Perhaps more research could be done to investigate whether DGIV can be eradicated or deactivated in cooler temperatures. The movement of ornamental fish through international trade is a major factor for the transboundary spread of pathogens. I have just gotten my first 20 gal tank for Christmas. Dwarf gourami iridovirus is apparently specific to the dwarf gourami (Colisa lalia), including the various fancy varieties of the species, such as neon gouramis and sunset gouramis. The study then concluded that southern pygmy perch “should be considered a potential host given more than half of the fish died with clinical signs of disease during the expected incubation period following IP injection, and there was evidence of viral replication.” (Rimmer et al., 2017).
