Gerald Bassleer examines a blue oranda goldfish with dropsy and wasting. Post-mortem shows black tubercles in the liver, spleen, and kidney, pointing to Mycobacterium, or fish tuberculosis. He recommends euthanizing severely affected fish and notifying the breeder.

Hello, Dear aist dear Goldfish keeper. The people who like fancy goldfish, like the oranda. I have here a case about a blue oranda that is infected in organs and causing, well, the fish to get sick, to die. So I will show you the fish, how they look like and what we find by using the microscope. And we found tubercles in the organs. Details on treatment, prevention and diagnosis of face diseases is available in my books in different languages. The link is below, where you can purchase them. Here we see the blue oranda in the pond. And some have dropsy, a bloated belly. You can see here is one. And some are behaving abnormal, swimming upside down, getting very irregular behavior. Some are wasting away. And there are some losses regularly, not a lot, but slowly, one each day out of the two, 300 is dying. So it's time really to check what is going on. And the first thing we found was in the gills, a serious bacterial infection. You can see here the necrosis, the bleeding part. So the gills were affected and of course that will kill the fish inside. We found in the organs, the liver, the spleen, the kidney, black specks. And here we took them out, we put them on our glass plates. You can see to the left here, the liver in the middle of the spleen, and at the right the kidney. And you can see already now the tiny black specks in the microscope. That's how it looks like here on the left, the kidney with all the black specks inside. And in the here the spleen, causing deterioration, malfunctioning of the organ. The same thing in the liver, badly affected liver. Of course this is giving a serious problem to the fish. And it's most likely mycobacterium or fish tuberculosis. We have not sent this fish to the laboratory. It costs time, it costs money. And this is what the importer or exporter has to decide if he wants to do it. But usually it's important to inform the breeder about this problem, because usually it's the breeder who is the origin of this problem. And that is something I explain in my separate videos on Mycobacterium. Look it up in my YouTube channel on Mycobacterium. Bunch it in and you will see several videos where I explain all about that. You can try to treat the bacterial infection because some fish might be less infected, have small amount of tubercles in the organs. And the gills need to be treated because they will die because of the gills are suff, which are suffocating. The gills cannot exhaust the ammonia or CO2 or cannot take up oxygen. The most damaged fish I usually do with dropsy. You better put them asleep, put them in our coast, because you cannot cure them. They're too far gone. So inform the supplier and the breeder because prevention planning is needed. And you can help these other fish, which are less infected with a functional fish food like Dr. Basler. Buy fish food Fuko, that contains fucoida. And that is a good help in repairing the fish. My books help you to understand the diagnosis, prevention and treatment of fish diseases. Training you can get at my Patreon. Check it out there. So I thank you for watching and trying to understand this particular problem with fancy goldfish or randa. It seems to be, well, a problem in our industry, so watch out for it. And any questions, put them down below. Maybe I can try to help you. Thank you for watching.
