Gerald Bassleer examines an Oranda redcap goldfish with tubercles in its organs, likely Mycobacterium. The fish showed lethargy, stopped eating, and had scale erosion and gill hemorrhage. Bassleer explains the infection probably came from the breeder or contaminated feed, with few treatment options available.

Hello, dear Akarist, dear fish keeper, Today you selected a video about an Oranda. Yes, a fancy goldfish, which is a popular fish that is kept worldwide by those that like. Well, a goldfish in the room in a nice aquarium. And it's also to be taken care of. Unfortunately, goldfish, fancy goldfish have been breeding and breeders, like I explained in my previous presentations on fish diseases, can also breed fish diseases. And that's why the breeder plays an important role in the prevention of these diseases. The access he or she can take in taking on good biosecurity, good quality measures. And that's why I want to share these videos with my findings on. Well, the fancy goldfish, what problems we find. So it might teach lessons in our ornamental fish industry. Here, an Oronda red cap with tubercles in the organs. Case 256. You learn more about fish diseases if you get my books. Yes, I have ebooks available. Also I have books you can take on in your hands. I would say that's the best recommendable. And I have it available in different languages. You can see the link below. Or you can learn about prevention, a good diagnosis and a good treatment for your fish diseases. Here we see the Oranda red cap. And most of them look normal, swim normal, do not show particular signs or diseases. Yes, most of them. But then you have one which starts to behave abnormal. Not swimming with the group, not eating well, separating. And then eventually the same fish is dying a couple of hours later, hanging at the surface in the corner. Sometimes you miss it, you don't see it. That's why you have to expect, expect daily your aquarium, your fish pond, once or twice a day, specifically during feeding and after feeding. That is quality time you have to spend because you fish have a language. And this one shows a language. I'm. I'm sick, I'm dying. Help me. You try to find out what I have and you can save my other friends in the aquarium. So we took scrapings from the skin and we saw this scraping on the scales. We saw a few flukes. It's only one Here we see very few skin flukes. We noticed that the scales had erosion and that is a specific sign for a disease, which I will talk about later on in my presentation. When you see this start to appear, that means that fishes getting in bad condition, no nutrients are brought anymore to the scales. And the scales start to deteriorate, to get eroded. It's a sign of a specific disease. The gills, well, the gills were also had a small impact of gill flukes. Very small. The gills were flamed and reddish. Here you can see getting some lamella which are fused together. See the reddish bleeding parts in here. And a few gill flukes. The gill flux was not the infection. But the main concern is all those bloody reds infusion, those hemorrhagic gills that is causing of course that the gills are not functioning properly anymore. And the main problem we found was in the different organs in the fish. On the left, the kidney with tubercles, the spleen with plenty of tubercles. Tubercles in the liver most likely caused by Mycobacterium. We didn't send it to the laboratory. It's the decision of the owner of the fish to spend money on it. Well, we know that if we find this kind of cases of tubercles in a fancy goldfish, that 95% is caused by Mycobacterium, which is a gram positive bacteria, usually caused by the breeding pair which are carrying the Mycobacterium, or by feeding fish food like red mosquito larvae that contains Mycobacterium. And this is hard to treat, difficult to treat. So what can we suggest for treatment? Well, some fish die, some can do better, have a good condition, particularly when you take good care of them. They can survive for a long time and have very little tubercles and very little damage to the organs. So they will do better. So we suspect bacterial effects are Mycobacterium. It is usually caused by the breeder. I would recommend if you see a fish suffering like this, which we showed here, to euthanize it gently because it's not possible to cure. Usually antibiotics are not effective against Mycobacterium, but some tried, some had success. Maybe it's success because there were very little infected, so they would have stayed alive anyway without treatment. You can ask your fish doctor or veterinarian or you can see my books where I describe possibilities to treat. But to be honest, I see very little result. It's more good actions by the breeder, preventative action that has to be taken. The few flukes we have found on the skin or on the gills are not yet an infection. But you have to watch out, particularly the healthy ones, which are little infected with the Mycobacterium, which have little tubercles. If there is an infection appearing because the fish are getting weakened, the other fish which are very sick can get an attraction of more worms, more flukes. So there might be a source, so watch out for it. At the same time you can help your fish with a functional food to stay better alive to recover better and we recommend in this case or Dr. Basler buy fish food. Fuko Diseases, prevention, diagnosis, treatments available in my books. Here is the link to my website where you can find out. The link is also below where you can click on it to order the books. Or you can get more training more advice about causes of fish diseases about carnitinic fish at my Patreon channel so you become more expert. So I thank you for watching this video on a specific case of an oranda with possible mycobacterial infection. Thank you for watching.
