Gerald Bassleer examines a black angelfish with split fins that aren't from fin rot or fighting. Microscopy reveals pale gills and nodular lesions in the kidney, spleen, and liver, pointing to internal infection, possibly fungal or bacterial.

Hello, dear aquarist, thank you again for watching one of my cases on fish diseases. And here it's about a black angelfish with split fins. Broken fins, Yes. A very special, unique case which I will explain here below in the next videos where I show you my examination and the use of my microscope and I will give you my conclusion. So watch until the end. So to learn a lesson about fish diseases. So I will share you my PowerPoint for you black angelfish scalari with split fins and internal infection. You can get more details in my books on fish diseases. Also about discus and angelfish. The black angelfish, you can see here the tail, how badly the tails are split. Also some dorsal fins are badly split, but it's not fin rot, it's not aggression. It looks like sometimes they're chasing each other, but they're not taking away the tissue from the tail or from the fin. So we took the fins and so we examined in the microscope and we couldn't see any necrotic decay or bacterial infection. We checked. We couldn't say that was a bacteria causing that. So it was not fin rot. We could see pale and damaged gills. That is a problem that can affect the fish. You can see here, some parts are completely rotten away. So bacteria can play a role here. So that you might have to treat. And internally we found in the kidney, in the spleen, in the liver, all those nodules, these inclusions, those capsules. It doesn't look exactly like a tubercle from Mycobacterium, but we don't know what it was. So there might be some other inclusions like caused by other viruses or a parasite? No, no parasite. Usually it's a fungus or a bacteria that can cause it, sometimes a virus. But the organs are very badly gone. And that might, of course, given the risk that the split fins are occur because the fish is weakening and the poor blood supply and the poor food supply to the fins causing this kind of decay of the fins, the organs with the nodules. Yes. A laboratory could help you in diagnosing it, particularly when you're a breeder and you're dealing with this kind of disease. Problem? Yes, presented. It might be ichthyophonus, for instance. Yes. Maybe that's a kind of fungal infection. The fish seems to hold on very well. Surprisingly, the fish are not dying massively. They kept on eating and swimming. Maybe an antibacterial treatment can help, particularly for the gills, that can support the fish for a better outcome. So maybe somebody has already seen this kind of problem on this angelfish. As a breeder and he can share his find findings. Always suggestions are welcome. So we can discuss this problem. I'm just a fish doctor working in my field and you might be having or your experience which is always helpful. So I publish some of my knowledge in my books that can help you to understand fish diseases. Or you can become a fish doctor and get your training at my Patreon. So I hope this also teached you a lesson about a split fin on angelfish not caused by a bacterial infection by an internal problem. Teach. Teach yourself using a microscope. Thank you for watching.
