So awhile ago my black moor goldfish got a fungus so I started using MarineLand All-In-One-Remedy. I used the whole bottle even when I saw the fungus appeared to be gone. Well I completely cleaned the tank and everything in it. Then a week later it came back and it almost covered his eyes. I had to finger feed him his flakes. Anyway I got another bottle and treated until it was gone again. I gave everything another cleaning and gave everything a peroxide bath, and changed his gravel. Then it came back AGAIN. Well this time it isn't to bad its in smallish patches and on his mouth. But it looks different, not so much fuzz like it was but more like white peach fuzz almost almost unnoticeable. So I went to my pet smart and asked what was the deal, what I was doing wrong etc. They said it might not go away completely and that I might have to keep treating it forever. I would mind to much but my family keeps telling me to flush him and get a new fish. Is there something I'm doing wrong or is he just going to be permanently sick?
 
You could try a stronger treatment, but yes columnaris can stick around forever. Even if you euthanise him (don't ever flush a fish, euthanise humanely and dispose of either by burying or throwing in the refuse bin), the whole tank is likely contaminated and you will just give it to your next fish. You'd have to completely dry everything and soak it in bleach to get rid of it.
 
I had 2 fish in there when it started because I was told it couldn't spread. I don't think the other one has it though. Is there a way to tell if it's improving at all so I don't have to kill him?
 
Can you post pics? I'm not a goldy keeper but they can be prone to diseases that can look similar...& treatments can be different for golds as well. I've had chronic columnaris in tropical fish...but, again, not a goldfish person.

I know they can handle salt dips for some issues...What are your water parameters? Ammonia, nitrate, nitrite? Tank size? Filtration? Water changes? Other fish? We need more info please.

So its around the mouth on the one with the small hole in his fin and right above the gills on the other. But I have a 10 gal tank and I do a 50% water change a day since I cant use a carbon filter with the medication. I currently don't have any test strips right now. And the only other animals in the tank are a couple of nertile snails.
 
Sorry for your issues, but just so we can get the big picture, how big is the tank, do you have a reading in PPM for ammonia, nitrite and nitrate and do you do weekly water changes?

These things are more important then adding meds to the tank and should be sorted out first IMO.

Its a 10 gallon tank and I don't have anything to test the water with until I can go to the store but I have the water test stuff from the last time I got it tested if that will help. And I do water changes daily like the meds told me to do.
 
Best bet is to mail order an API master test kit if you can't find one locally or don't want to pay the retail price. They're $25 or so mail order, but will last you for years.

Sounds like you're on the right track with 50% water changes often, with a quality dechlorinator product like Seachem prime or safe.

I'm not really up on meds given I've been lucky to not have anything I couldn't cure with good water parameters.
