Fungus will not die!!!

[wsauve]

Hello Folks:
I have a small Koi that I thought had fin rot and fungus on his dorsal fin and his tail. I put him into a 10 gallon tank and medicated him with tetracycline for a week. His problem became worse so I changed the water and added salt and began treatment with malachite green. After more than a week of treatment with malachite green, the condition became worse so I ordered some methylene blue online and continued with the malachite green treatment until the methylene blue arrived. I gave him a good dose of methylene so I was hardly able to see him through the blue. After a week and the condition worsening, I started treatment with Pimafix. No luck. I am currently using Kordon Fungus Rid. After about 4 days the condition appears to be getting worse. I have read about phenoxethol but I have been unable to find a supplier.
As you can see from this post, a lot of time has passed and this fish is still alive. He behaves like a healthy fish, very active, but he is looking rough. At this point, I have no alternative other than to continue with the Fungus Rid and hope for a turn around.
Is there anyone out there that has had a similar problem and successfully treated the fish? If so, with what ?
Bill

Me waves to a fellow Washingtonian !

I have koi and have dealt with this problem. I'm assuming it's columnarius (it's actually a bacterial infection). It basically looks like "Cotton" growing on the fish.

You need a strong oxidizer if nothing else works. Try to get your hands on some potassium permanganate (can usually get at a pool supply store).

Make a paste with the PP and apply to the infected area. You can immediately put the fish back into the pond if needed.

Having good water parameters is key to preventing this and allowing it to heal. Make sure you have no ammonia and do frequent water changes.

Good luck and keep us updated!

The main thing is to keep changing the water with fresh, You can still medicate, although my instinct is that you are overmedicating at this point. I have had the same issue with comets I am watching for a friend, they are looking way better after a Primafix/salt for a week treatment, and maintaining pristine water-like 50% water changes 2x a day with adding salt to the dose of a teaspoon per 5 gallons. The Primafix is nonexsistant a this point, but salt treatments continue. These fish look many times better than they did when I got them...

Let the meds do their thing and slowly remove them with water changes, you have good water-albeit a little soft for most fist-I live in Covington and deal with the same conditions as yourself. I you'd like you can keep your fish in my 50 gallon with these other 2 nitwits! They have been 'hospitalized' for 2 weeks now and are getting cabin fever! lol...

BTW Welcome to THE spot on the net for fishkeepers in the know.

Oh, and OXEGENATE THE WATER! get as many pumps as you can afford and get the O2 flowing...

The issue here is your constant switching of meds. Your fish may have survived so far but the more you change the meds, the less likely your fish's issue will get any better at all as the fish is constantly stressed thus discouraging it from likely boosting its immune system enough to repel any infections it may have.

If I were you, get rid all the meds and stick to salt only for at least 10 days. See if that alone and water changes will make any difference to the condition it has. Please keep your fish well fed at this point and regularly check your water parameters.

How did you dose salt?
