Columnaris treatment?


About a week and a half ago, I bought and added 5 Cardinal Tetras to the 4 I had to begin with. Since adding them, I've lost I think 3 of 7 CPDs and probably 4 Cardinals over the last week, with seemingly no symptoms.

Today, I noticed what looks like a little fluff of cotton on one of the Cardinals at the distal base of the dorsal fin. This reminded me of a sickness that I had when I first established the tank a year and a half ago. At the time, someone on here mentioned that it sounded like columnaris. I had no definitive proof that it was columnaris but I treated the tank with something called Furan-2 (I think) from my LFS and it cleared everything up.

I was planning on treating this as I did my "columnaris" infection before. My LFS is closed on Sundays so I went to Petco and purchased API "Pimafix" which was the only product they had to treat fungal infections. Does anyone have any experience with this product?

Also, I have some Amanos so I need to be careful about them too.

1. columaris is not a fungal infection
2. they're different chemicals. Pimafix is only for preventative applications.

FYI Petco does not carry any real fish meds anymore such as anitbiotics- they stopped a few years ago. Petsamrt still sells them.

FYI, Furan-2 aka Nitrofurazone should not be used with amanos in the tank. Invertebrates can be killed by this specific antibiotic. As for the columnaris, a combination of Furan-2 and Kanamycin worked great in completely eradicating it.

How much of each is used in the combo?

I am also trying to get rid of a suspected columnaris outbreak: do I add full amounts of each antibiotic, based on instructions, or just half? I would assume full amounts of each

I just follow the dosage directions on each package and dose them at the same time. Never use antibiotics at diluted strength. You'll create antibiotic resistant strains of the bacteria. Also, always do a full course of treatment. Don't stop halfway once the symptoms disappear.

I figured so. Also, is this a "whole tank" treatment, or move the fish to a hospital tank? I'm curious because I don't know who all is actually sick (they die over night randomly and lose their fins), so I don't want an incomplete treatment because I missed a fish or something like that.

Dose the entire tank if you aren't sure who's infected. Besides, the bacteria is already in the water column.

Is there a tx I can use that is safe for the Amanos?

You're going to need to use strong antibiotics so no. Hope for the best.
