Gerald Bassleer examines a blue marble gourami with lymphocystis, a viral infection. Diagnosis comes from skin scrapings showing enlarged giant cells. Since antivirals don't work on fish, treatment means better tank conditions and immunostimulant feed to help the fish fight it off.

Hello, dear Akarist, welcome to my video number 171 about a gourami, a trichogaster, Trichopodus trichopterus Cosby, the blue marble gourami, suffering from a viral infection called lymphocystis. And that is something, well, we have to watch for because it happens and sometimes we see it clearly. Well, lymphocystis here is explained the terrible infection and explained a lot in my books. Yes, the books give you a lot of information on this lymphocystis with a lot of more photographs in this case. Well, it was not so obvious to see. We only could see some bad fins and the fish was getting skinny. Yes, not much to see, but it tells you that our eyes are very limited. We could see some damage here at that. Well, dorsal fin. Well, that's all we could see. We could see skinny fish, see. We see more observation here of the fish which were not bad, not good formed. But could we see an infection? Well, I couldn't. I could see some bad fins, that's all. But when we took a scraping here from the skin, we saw those giant cells. See the yellow things here inside? These are giant cells, cells blowing up caused by a virus particle inside. That's what happens. And that makes the fish looking bad and getting maybe sick later on, getting weak and die. First of all, we have to realize that viral infections cannot be treated. You can control the fish health of the fish so it can become strong and build up immunity against it like we do by humans. Strengthen the animal, strengthen the human to fight off viral infections. And fighting off the secondary infections like bacteria or even parasitic infections can appear later on because of the weakening of the fish. So you have to provide very good conditions. So avoid all the stress and apply a good immunostimulant in the fish food to strengthen the resistance of the fish. In this case, we recommend Dr. Basler Baizerfood Forte to help to strengthen the fish. And the sooner that you act, the sooner you take your actions, the better your results will be. These also I explained in my books you can get. So this short video about this Gorawie with a lymphocystis infection should have teached you another lesson about fish disease. Thank you for watching.
