Gerald Bassleer presents a clinical case (Fish disease case nr.165) of a wild killifish species Aphyosemion bivitatum collected from Nigeria that showed weakness and mortality. On examination he observed necrotic damage to the gills consistent with a secondary bacterial infection and found encapsulated worm larvae in internal organs—likely acquired by eating wild food—leading to liver damage and immunosuppression. He advises there is no specific medication for encapsulated worms, recommends stimulating the fish immune system (e.g., Dr. Basler bifish food) and, when necessary, antibacterial treatment; refers viewers to his books and other videos for more detail.

Dear Aquarist, dear fish keeper, thank you for watching this video on achillifish. Yes, azemium can also get sick. And I explain you a specific disease which might interest you when you're dealing with wild killifish. So watch my screen that I show you my videos and my findings while working as a doctor. The fish disease case165 about Aphismium bivitatum, a wild one with a worm infection and secondary bacterial infection. Watch my videos and watch my books. In the books I explain a lot about killifish and how to cure and how to treat. Well, this is a killifish, you see. The bivitatum came from the wild, came from Nigeria. It looked weak and some were dying. Not particularly any disease symptom typical to observe. We checked the gills and we found that there was a bacterial effect. You can see here the necrosis here. Parts are eaten away by the bacteria and that is of course causing damage to the respiratory organ. And the fish can die from that internally. Well, you can see we found some organs in the organs. We found some those kind of enclosed worms, a little worm larvae because the fish are taking it up by eating that kind of wild food. And that can contain some worm larvae or eggs. They become larvae. And then if the fish is eaten by a bird or a live food, it closes the cycle, it become an adult worm. So it creates a bad liver. Well, that is what you can have with the wild fish. And that you can have these kind of worms inside by eating the wild food. That's what happens with a killifish and he becomes weak and he can get secondary bacterial infections. There is no medications particularly to control those worms because they are encapsulated. Try to stimulate the immune system. Because some fish have very few worms, they can survive. Well, they do well as long as you strengthen the fish. And therefore, we recommend a specific functional food like our Dr. Basler bifish food. Forte bacterial treatments, yes, might be necessary that you apply an antibacterial treatment. Ask your pet shop what products you can get because the diseases can advance and kill the fish eventually. And some fish, yes, might be too weak to be saved, especially when they do not longer eat well. Well, more info and details on my books you can get that. So learn. Learn fish diseases.
