Hello! Recently, my guppies are developing swelling stomach, decreased to no appetite, trouble swimming, and paler body. I noticed a red string intruding from their anus I diagnosed it as intestinal worm. (camallanus worm) I am thinking about using the Panacur method which mixes panacur (a common livestock dewormer) with water and soaking bloodworm in it for the guppies to eat. The only problem is that one of my guppies are probably at a more advance stage because she refuse eating all together. I could pour the water with panacur in it, but I am not sure how well that will work. I have a 6.6 gallon tank with trapdoor snails, malaysian trumpet snails, 2 african dwarf frogs, 3 guppies, and 1 guppy fry. 2 of the guppies are showing symptoms of the disease and I can see the worm sticking out. However, one of them is still eating. The last guppy didn't show any sign but it is probably infected as well. 1) Any idea or suggestion on how to treat them with Panacur? 2) What should the dosage be? The drug I am using is 100% fenbendazole (panacur). 3) How would I treat her if she wouldn't eat?
