FlyingFishKeeper Posted March 20, 2021 Share Posted March 20, 2021 Hi, randomly I was wondering why our aquarium fish don't seem to contract viruses, or do they have symptoms similar to a parasite, fungi, or bacteria so we don't notice them and end up treating for those? Thanks! Link to comment Share on other sites More sharing options...
Colu Posted March 20, 2021 Share Posted March 20, 2021 (edited) They get virus such as viral hemorrhage septicemia and DGRI iridovirus or carp pox or koi herpes virus some have symptoms similar to bacterial infection fungal infection it very difficult to diagnose what type of viral infection your dealing with most of the time you just have treat the secondary infection they cause Edited March 20, 2021 by Colu 1 Link to comment Share on other sites More sharing options...
Daniel Posted March 20, 2021 Share Posted March 20, 2021 Everything including fish (and humans) are rife with viruses. Up to 8 percent of all human DNA comes from viruses and I wouldn't be surprised if it were the same with fish. But just like with humans most viruses are not deleterious to fish. That being said I think the reason we don't worry about viruses and fish is that there is so little that can be done by way of medications. Anything that can be tweaked like pH or nitrates we go at hammer and tong. If there were a mythical medication 'Virus-X' it would be recommended for every shimmying guppy and every bloated betta. Every fish whose fins were deteriorating in poor quality water would get a dose. The only questions would be 'Is Virus-X' shrimp and snail safe?' and 'Why can't I get 'Virus-X' in Canada?' 4 Link to comment Share on other sites More sharing options...
gardenman Posted March 20, 2021 Share Posted March 20, 2021 Viruses in koi were a big deal a few years back (probably over a decade now). Whole koi farms and ponds were wiped out. Most koi producers now test regularly and certify their koi as being virus-free. 1 Link to comment Share on other sites More sharing options...
