I think that is (sadly) columnaris. I don't know what I can tell you that can help you. >.< I've dealt with literally every diasease but this one! I'm sorry! If it reaches his body......

 

That's what I was afraid of

 

I have dealt with Columnaris and it is a yucky horrible disease!

This is a site that gives you a lot of information about it:

and another site I found helpful:

One of the vet techs will hopefully come on and tell you if they see columnaris in your fish.

If it is Columnaris you will want to treat with KanaPlex and Furan 2 as well as AQ/MB baths nightly. That is 9 drops Methylene Blue to 1 teaspoon Aquarium Salt. You will want to start the treatment asap but first you will need to be sure it is Columnaris. I hope that this info helps! (it looks like Columnaris to me too)

This stuff is so contagious! I cleaned everything with Bleach and salt, dried it and then cleaned it with hydrogen peroxide just to be sure I finally got rid of it. I sure hope that you can get him started on the treatment right away.

If you don't have Furan 2 you can use Jungle Fungus Clear as it has the ingredients in it also which can be purchased even at Walmart.

 

Hello! So, I did a round of Furan-2 and Kanaplex. Waited a few days and did methlyne blue baths with AQ salt. Thor was doing better and even had some tail regrowth. I've been keeping him in a 3 galling with every other day water changes. It was going well until a week ago when I noticed a white fuzzy spot on his body. I immediately started Furan-2 and Kanaplex (I did a total of four more doses each). Now he is in unmedicated water, but he now has some discoloration around his eyes, the same white spot on his body, and I've noticed some white fuzz in the water. He's still acting and eating fine. Is there anything else I can do???? I will add a picture tomorrow.

 

Please post a picture so that we can see that white spot. So you are saying it went away with the KanaPlex & Furan 2? You stopped the treatment and it came back, correct? You should be doing nightly MB/AQ salt baths with the meds as it helps them to work better. Columnaris is a difficult bacteria to get rid of once the fish gets it. So please post the pictures so that others can help too! Thanks!

I sure hope that we can help your lil guy!

 

I bought a fish with columnaris and treated him with such strong salt baths that he passed out in, but it got rid of it.

 

Oh my gosh I thought the photo was posted days ago! I guess it didn't go through on my phone. The first photo here is the one I originally going to post, the rest are from tonight. It seems like the white spot has decreased in size. I've been keeping him in 1tsp per gallon with every other day 100% water changes.

 

I am having trouble seeing if it is actually Columnaris but lets treat it as if it is because he is rebounding which is typical of this bacteria. I wish one of the Vet techs or someone with more medical expertise would take a look at your photos. If it is the salt will help kill it. How many rounds of KanaPlex and Furan 2 have you given him? (A round is one complete cycle of medicine that is recommended.) The one thing I found with my guy was that he would get a little better and I would stop the treatment and it would return. I found out that I should have kept giving the meds until it cleared up and go another round after that. You do have to be careful not to overload his lil body with meds but you do have to give him enough to get rid of it and it is a booger of a deal to get rid of. Keeping salt in his tank is good but you can't go more than 10 days doing that without damage to his internal organs from what I have read. The MB/AQ baths can be used indefinitely and aid in the KanaPlex/Furan 2 in doing the job of killing the bacteria. I had to give my fish nightly baths for months and I believe that is why he lived so long with the disease. You might also try feeding the KanaPlex internally as that gets in his system better. Is he still active and swimming around?

I don't think treating with salt alone will get rid of Columnaris. I have read about people doing the high salt until the fish passes out too but you can also kill the fish doing that if you aren't extremely careful. Also one of the articles I read by a gentleman that is greatly admired in Aquarium circles claims that if salt baths cured your fish it was not Columnaris but another disease that is sometimes confused with Columnaris.

 

Hello! Sorry for the delay in an update. In the last couple months I graduated college, enrolled in graduate school, got engaged and I'm in the process of moving into an apartment with my fiance. I did more salt baths and then have just been keeping his water clean (every other day full changes). He is doing well and is slowly gaining fin regrowth. He is staying in the hospital tank until I'm sure everything is gone. Thank you everyone for helping!
