Sick blue oranda & black telescope?

It look maybe my blue oranda has picked up something. Perhaps the stress of being lonely lowered his resistance. He's still bottom-sitting, but this morning, he was showing signs of distress- rapid breathing and the edges of his tail fins are losing color and fraying.

Also, one of the new baby goldfish I just acquired has a few white patches on his skin- not solid white, but regions of patchy whitishness- one on the top of his body, another on the side. They don't look fuzzy or cottony, and no film is streaming off. His dark bronze color has faded to light bronze gold on the lower part of his body.

Tank is cycled, and is currently being treated with flubendazole. Temperature is about 75F. Last Water change was Sunday. I could not test the water before I left for work this morning- I will tonight.

Here is a recent thread from the coldwater forum that gives a bit more history on the blue oranda:

I was starting to suspect columnaris in the baby fish. I was thrown off because it appears very different from what was diagnosed as columnaris in a betta that I had about 2 years ago (on another forum).

With the blue oranda- he was purchased about 18 months ago. During that time, it has never been treated with anything and always appeared healty. He lived with two other goldies at my parents house- both of which were purchased a year earlier than him. Recently- those two fish passed within a day of each other. I had visited my parents about 10 days before the first death and all looked fine- active, swimming, etc. I believe that those deaths were caused by a power outage- after the 2nd fish passed, they called me and I came over to help them with their tank. The filter was septic- my guess is that this happened during the power outage.

I took the blue oranda home, and he appeared depressed- he was bottom sitting, but showed no signs of any illness and was eating well. I got him a friend to hopefully perk him up and treated the tank with flubendazole. That new goldie died after 3 weeks. I just purchased 2 new babies goldies and treated with another round of the flubendazole. The oranda is now showing signs of distress- bottom sitting, heavy breathing- gills and mouth opening and closing.

It appears that I have two different issues.

How should I tackle this? I've got kanamycin on hand which I think would be appropriate for the columnaris. I've got flubendazole and jungle parasite clear tabs which I could use for flukes. Should I treat one then the other? If so, what order? Can I use a combination of these meds at the same time? If not, is there another combo that would be effective/safe? I know I have used kanamycin and formalin/malachite green in combination before.

I have two spare 20Gs and 1 spare 10G, so if necessary, I can move the fish to separate hospital tanks. Should I consider moving them all to a single or multiple tanks and nuking the current tank?

Here are pics of the baby that is suspected to have columnaris:

For now, I am going to do a large water change/gravel vac. That way I'll be prepared to medicate when I know for sure what meds to use and in what combination.

I am sad to see him in this state too. He has been eating well and only yesterday began to showed white patches- it became worse overnight.

I always QT my new fish. But this time, I didn't. I misunderstood the posts in my prior threads- I interpreted them as recommending that I add the new fish in with the blue oranda (to ease his stress by giving him company), but to treat him and the new fish for flukes together as a precaution. This was my misinterpretation and my mistake.

Just to make sure I understand- you suspect that the blue oranda has carried flukes since he was acquired and because he was never treated. The flukes carry the columnaris bacteria. The young fish picked up the columnaris from the flukes. Now, I must treat for flukes before columnaris because flukes are the primary issue. The columnaris is secondary.

I live in New Hampshire, but the local fish stores are poorly stocked. Parasite Clear was the only medicine I could find with prazi in it. I happened to have flubendazole in my fish med cabinet. I bought it to treat a suspected parasite in some wild-caught cichlids. I can order prazi, but it will take a few days to get here.

My pH runs high- around 7.4-7.6, so I should be okay with Kanamycin.

Since all the fish are together, I assume that they are all exposed to columnaris, so they should all be treated together.

The papers I've read say to do a water change, add Flubendazole, and then do a water change after 3 days. When can I add Kana into the mix?

I've avoided salt up until now because the tank is planted, but at this point, I don't care about the plants. Would salt be beneficial? Should I consider a salt dip for the black moor?

There is so much information out there, it is hard to know exactly what to do.

Thanks. I haven't made gel food before, but there is a first time for everything. I've printed out the recipe you recommended. I'll pick up the ingredients while I'm out today and give it a try.
