Do these koi have worms? They have been like this over the winter, it started shortly after I fed some tubifex worms. Over the months I have treated multiple times with Prazi pro, prazi/metro medicated food and currently feeding metro/focus and garlic guard food. They have had white stringy poo in the past, and currently on and off. But not a lot when I do weekly water changes. I was going to put them in the pond, but I am scared they will infect the whole group. Which would be a disaster. Please any help as to what I should do with them? They are to big for that 55 now. The little one has had this scale less head forever and never grew. Should I add a de-wormer such as Fenbendazole with focus to food? How much per Tablespoon food?

I don't know that we've ever seen pictures of fish poop on the forum before! I think the fish look fine, but haven't ever studied them at quite that level before! I would suspect that the medication is creating the "output" changes you're noticing. I'd be hesitant to medicate them any more - at some point you're destroying their natural defenses.

Why are you medicating them so often? Was there some sign something was wrong with them?

Yes the yellow swollen one and multi colored was spitting out food unable to swallow. And the little one was always hiding. They still don't eat like my other ones, but they are swollen, their vents seem protruding.

"Unable to swallow" or food to big for them? My goldfish would grab the big floating food and then spit it back out because it was too big. It seems those fish would be in far worse shape if they were unable to eat.

I am no expert, but I have seen all shapes and sizes of poop from my goldfish over the years. Here is a link that might be helpful. Scroll down to the bottom where it discusses “internal parasites.”

Pellet size is small and I crush it a bit also. They were spitting it out

I didn't see the link. Where is it?

Sorry about that!

Thank you. But it doesn't tell me how to rid them. They have the swollen belly.

Actually, it did. It said to let a vet examine the stool. To treat something, you have to know what’s going on. Is it internal parasites or is it something else? Maybe take a stool specimen (a fresh one) to your veterinarian and let them do a fecal float test. If it’s negative, then you’re not dealing with an internal parasite. If the fish is female, she could be ready to spawn or be egg-bound. The fish could have dropsy. It could be a tumor. My philosophy is to not blindly treat. There may not be anything there to treat, or you could be treating for the wrong thing. Personally, I think your fish look healthy, but I am far from an expert. Have you done a Google search for “stool abnormalities,” or “koi with swollen belly?”

Over the months I have treated multiple times with Prazi pro, prazi/metro medicated food and currently feeding metro/focus and garlic guard food.

I still wonder if it's the amount of medicating that you're doing that's causing the results you're seeing. Prazi will cause the white stringy poop from my limited experience using it.

Yes I have researched. I will check with my vet and see if they can do the stool test for the fish. They don't treat fish there, but may do the sample.
