I have breed some leopard discus and some blue diamond and some blue turquoise discus. The fry when taken off the parent’s bodies after a few days turned dark. I tried praziquantel, metronidazole, salt and all medicines but one by one they turn dark and die. They show very little scraping against tank or objects. Please advise me how to treat them and get rid of the flukes or any other disease parasite or worm or bacteria. I am also using tetracycline and acriflavine. The tanks are kept very clean.
1. When do you transfer your fry, or after how many days free swimming? How big is your fry?
2. If you are not sure how to take care of the fry, let the parents do it. The fry can grow until 1 to 1.5 cm with the parents.
3. You can only apply Methylene Blue solution after laying eggs and while nursing the fry. The fry are too delicate to take other medicine.
4. To transfer the fry you must be careful not to stress the fry: The water temperature and pH must be the same and no chlorine.
5. To deal with gill fluke, Potassium Permanganate (PP) bath is the most effective.
6. If the fry always turns dark and get sick is the parents that give you problems not the fry.
7. Give all your breeders a PP bath every mouth. They should be free from bacteria and parasites. Give them worm treatment too.
8. Happy breeding and expecting your feedback if there is any improvements.
