This is a single-case YouTube video by Gerald Bassleer (case #167) describing disease in a barb (Desmopuntius pentazona). Bassleer documents external clinical signs (skinny fish with sunken bellies), gill damage (missing lamellae), and microscopic detection of small, fast-moving parasites identified as Cryptobia (Cryptobia branchialis), with secondary bacterial infection of gill tissue. He explains differential behavior vs. Kostia/Ich, and recommends antiparasitic and antibacterial treatment alongside supportive measures (gill repair, immune support) and his own products/books for dosing guidance.

Hello, dear Acrist. Welcome again to my next cage of fish disease. And today it's about a barb, desmopuntious pentazona. And I show you some specific details. That is a specific parasite we sometimes can encounter in fish. So watch my video and I explain you also how to treat or what you can do about it. And this is already an advanced case in my studies. 167 with parasitic infection, cryptopia on this desmopuntious pentazona. And also a secondary bacterial infection. Yes, that can happen. And I explain a lot about those details in my books. And that's how the barbs look like. And some look skinny. Well, if you know, you watch your fish very closely, you will understand when your fish get skinnier. You here see a few barbs in between the other ones that are getting skinny. They're getting a sunken belly. And some are active and are less infected. And some other ones are suffering more. You can see, look at the skinny ones in between. If you know it, you can see here is a skinny one who swims away. And here is a skinny one. That's what's happening. See the skinny ones here, another one here, the sunken bellies. That's not good. That's you take out for sample examination. And then we checked on the gills and we found that the gills, look at the tips of the gills are gone, the lamellae gone. And here's some bacterial infection where they took away some lamellae. So we have to use a microscope and show you a video what I found here. And well, I go to a higher magnification because they're very tiny, small parasites. They're called cryptobia. And if you watch closely, you see them swimming rapidly. Very small, tiny parasites look a little bit like Kostia. And they're moving away and very fast and attached to the tissue. And I show you on another video, which you can see him here sitting. You see it here, see them moving, see them getting away very fast. So this different behavior than Kostia. So it's a different kind of a parasite. It's a cryptobia. So what can you do as a treatment? Well, you understand, as I showed you, the cryptobia damages the gills and causes secondary bacterial infection, infections. So you can use an antiparasitic treatment, an antibacterial. What is recommended? It's recommended in my books. Try to help the fish with a good repair of the gill tissue and improve their immune system. And for these cases we recommend or Dr. Basler biofish food, Aloe vera. So the books can help you to understand. That's why I made the books to help you to understand fish disease and to apply the correct treatments and the correct dosage. So I hope this helped you to understand fish diseases in a particular case on this barb with a Cryptobia branchialis infection. Wishing all the best to take care of your fish. Thank you for watching.
