A Gerald Bassleer YouTube case presentation (Fish disease case nr. 136) describing a bacterial infection in the golden Aphyosemion australe (killifish). The video documents external clinical signs (emaciation, clamped tail, stumbling), skin-scraping microscopy showing motile black bacterial colonies and damaged gill lamellae (loss of lamellae), and necropsy findings of necrotic liver and spleen. Bassleer advises urgent antibacterial treatment (antibiotics/antibacterials available from pet shops or veterinarians) and supportive feeds/supplements (Dr. Bassleer bison food, grapefruit seed extract, moringa). He also promotes his books, website and Patreon for further case coverage.

Dear Agmarest, good day. Welcome again to my YouTube channel and to watch one of my videos on a case of fish diseases. And today we will talk about achillifish. It's about an aphiozemian australae, the golden variety, which has a bacterial infection. Well, I'm sorry, I already explained you what the disease will be. But still interesting for you that you see what I did find in the microscope and what kind of problems I could detect and what kind of suggestions I can do for treatment. So watch my video and tell me what you think. If you have any critics about it or any opinion. But if you see this kind of fish like this, a few semen here wasting away, you can see here its tail is getting clamped and the fish is in very poor shape. Some other ones are in very pretty good condition. But look at this stumbling fish. It's time for you to take action and don't wait, because the next day half of your fish could be dead. That's how terrible certain bacterial infections can be. And we took a skin scraping and here I show it on the video. You see here the scales, and here you see all those black deposits. And here you see at the bottom also all these black parts is colonies of bacteria. All those black little tiny spots in the water which are moving or trembling. There are also some white ones. Usually there are two or three different types of bacteria that play a role in the infection. So, and in this case it was very clearly the black ones, which you can detect as a group or a colony in the gills. We could see that there was some transparency here. Here is the darker parts, which is not always good, but it at least is better than those clear parts. And here we see it in a higher magnification that those lamellae here are gone. So there is no possibility for absorbing oxygen or expelling CO2 or ammonia. So that's a bad gill that is giving a serious problem to the health of the fish. And then we examined internally the organs and we saw necrotic areas here in the liver. Look, how bad does liver look? This is all caused by bacterial infection. Look at the spleen, a lot of necrotic areas. So you can see the pathology of this organ is in very bad shape. So our conclusion was with like here, another killy which was already having white patches here, you see it on the picture? Well, it's to start the treatment as soon as possible because the sooner you act, the more fish you can save, as long as you're still eating and being healthy enough. To accept the antibacterial treatment because you have to do an antibacterial treatment. You can get those kind of treatments from your pet shop, aquarium, or ask your fish doctor. Sometimes a good antibiotic can also be a help. And at the same time, you can help your killer fish by feeding with our Dr. Basler bison food, grapefruit seed extract, the moringa, which is helping in the control of this kind of infection and help the repair of the fish. So you want to learn more? Well, get my books in different languages available through our website. You can order online. Yes, you can become more informed or go to my Patreon channel or follow more cases in my YouTube channel. So I hope this video explains you in this case on the killifish bacterial infection, but more infections will be explained in further cases. Thank you for watching.
