Hi all, just wanted to let everyone have a warning. Most of us are at least somewhat familiar with Iridovirus (Dwarf Gourami disease). I just heard from a friend on facebook that Iridovirus is now crossing over to South American species. Previously the virus was only found in Asian species. Most of them had natural immunities to it. South American species do not have any antibodies for the virus, as they haven't been exposed to it before. The virus has been found in south american species sold at the big box stores all over the US, indicating that it likely originates at the farms they buy from. Guppies appear particularly susceptible, as well as the more sensitive corydoras species. The virus takes several months to manifest visible symptoms, so it can get past the standard QT. Initial symptoms are red, swollen gills, loss of appetite, and erratic swimming. There isn't a cure, but apparently Iridovirus is a retrovirus. My buddy once worked in healthcare and had some old HIV meds lying around from earlier days. Apparently he had success using some of the antiretrovirals to treat one of his tanks. But, there's no treatment commonly available yet. Anyway, I'm gonna see if he can send me any documentation on the issue, but just wanted to get the warning out there.
