Fish disease case nr. 158 Cardinal tetra with bacterial infection in the gills and internal

Hello, dear Akarist, today we have a nice background, well there of nice cardinal tetra and a show tank at one of the trade shows I attend. Well, this was a beautiful showcase because I'm going to talk today about the cardinal tetra. Yes, cardinal tetras are very popular fish in our industry and in the hobby. And of course there are so many available. Of course there are also many problems to report. So stay tuned and watch my video where I show the diseased fish by microscopic observations and my suggestions what you can do as a treatment. So I will share my screen with you. And we talk today about a bacterial infection, particularly the gills. I will show you how that looks like. Well, first of all, I promote my books on fish diseases. Also part carnotetra, where I explain what you can do, how to diagnose, how to understand fish diseases and how to treat. And here we see the cardinal tetra, which we took out of the aquarium. Some are very skinny and those were dying. This one is starting to get skinny. In the coming days he will also be looking like this one here. And that's once we take out to do an examination. We could find here in the gills, you see the black accumulation parts covering the lamellae, bad functioning of the gills. That's the problem that will arise. And internally we also find a bunch of bacteria. So let's go in detail and I show you the video here on the gills of the fish, all those black colonies and all the millions of bacteria in the black little dots swirling around, moving around into the water. So they are covering the healthy tissue and not allowing good respiration. Here we see more bacteria, different kind of bacteria, little stag bacteria here, many bacteria over here, all the black spots. We see one little organism moving here. Well, that might have been flagellate, maybe parasite, but if it's only one, it's not an infection. That is common in damaged tissue because here the tissue is damaged by the bacteria. And then you can have some invaders, not particularly parasites, but other little animals that protozoa that move in to do that affected tissue. And internally here we in the abdomen, we found all different kinds of bacteria with rots, with spots, black spots, whitish spots, many different kinds of bacteria, which is causing of course, an infection in the organs, not only in the gills, but also internally. So our conclusion was, well, we have to apply an antibacterial treatment as soon as possible. It can be an antibacterial drug you can get from the pet shop, or an antibiotic you can ask from your vet or a fish doctor. Check the origin of the problem. It might be poor stocking, too many fish like overcrowding, poor water quality, poor handling of the fish. And I would recommend to strengthen the immune system of the fish with a functional fish food like our Dr. Basleer Baisherfoot Fuko or the grapefruit seed extract with Moringa or the professional treat. So different kind of food that helps the fish to recover and to do better in the coming days and weeks. Learn more about fish diseases in my books. Like I said in the start, I conclude also with the recommendation if you want to be a professional fish care keeper, go to my Patreon. There is an opportunity to become trained, to get a training as a fish doctor. So I hope this information on this sick cardinal help you to understand what kernels can suffer from and what you can do and take as actions to keep them healthy in a better condition. Thank you for watching.
