Gerald Bassleer presents a fish disease case involving a Colombian Silver Shark (Sciades seemani) with a bacterial gill infection. Using microscopy he observed severe loss of gill lamellae, diagnosed a bacterial cause (no gill flukes), and advises prompt antibacterial treatment, good water/food, and references his books and products for further guidance. The video emphasizes microscope-based diagnosis to avoid incorrect treatments.

Hello, dear Akarist, welcome again to one of my cases of fish diseases. And I may be wrong, but it's highly unlikely. Yes, because I used a microscope and I checked this fish when it was presented to me and I found the pathological reason leases the damage to the fish. Of course you can discuss my findings, you can discuss my observations, my suggestions for treatment. Yes, put it in the comments. And I hope I can give you an adequate answer. Because science is never settled, we can always learn and continues to learn. It is very important that we follow the signs but remain critical so we can debate what we do in keeping our fish. Particularly when you are a hobbyist, watch out for the bad information you can see on social media. And try to learn to follow the good interesting channels like mine where I tell you what I've diagnosed so I can give you the good recommendations for the treatments. That's all. What's in it? Good diagnose, Correct diagnose and your findings decide what treatment you can give. And today it's about the silver shark. The silver Colombian is silver shark. It's called the Sciadis semani. The Colombian silver shark, which has a bacterial infection with gill rotation. This fish used to be called Arius semani. It's now the Schiades silversark Semani. My books on fish diseases help you to understand the diseases of our fish, how we diagnose, how we prevent and how to treat. And they are available in different languages. The link is below, where you can order them available in the description. And this was the Sciata semani presented to me, which was very skinny. He's going to die. He got difficulty to swim. You can see how that slender body. Well, he will not live for a long time. And some of his friends in the aquarium were still in good condition. Yes, not all of them, some in the back were also starting to suffer. Some of the ones with good belly, well, they're still eating well. But the skinny one I showed was not eating. And then we diagnosed on the skin. There was nothing we could find as specific as pathogenic to show you. But we found badly affected gills. Look at this. How many lamella are gone? Eaten away by bacteria. See this kill. Nearly half of it is just disappeared. And you can imagine what kind of problems this fish will have. He will become weak and not eating well. And your access has to be treat as soon as possible against the bacterial infection. Of course, good water and good food is also important to help the fish to stay strong against the disease. Ask your pet shop or your fish doctor or vet for a good medication or see my books. I explain a lot about medications to treat bacterial, infectious and you can help with a functional fish food that helps the repair of the fish. And we could suggest here in this case our Dr. Basler Bifish food aloe made from aloe vera. My books help you to understand fish diseases and how to take actions, try to get them or become a Patreon member to my channel and learn how to diagnose. Follow my courses on quarantining fish, how to learn about the causes of fish diseases, all practical courses that make you more professional. So I hope this video helps you to understand that fish diseases can be found when using a microscope. Just by the naked eye, seeing that skinny catfish, it's a guess you're going to take. You might start to treat for flukes, gill flukes. A lot of people do that here. There was none involved, plus only bacteria. And if you would use just a fluke medication, the fish will eventually die because you didn't take the appropriate action, not the correct medication. So I hope this teach you a lesson. Thank you for watching.
