UnKnown Fish Illness Killing all my Fish!!

[Krest]

I have a 10gal fully cycled and planted guppy tank it’s been going great for months until a week ago...
One of my female guppies developed a pale whitish grey stripe across her body vertically. I transferred her to an empty cycled 5gal tank and dosed Seachem Paraguard. Two days passed getting worse each day and she died. Then I start noticing nearly every other guppy in my 10 is starting to show these same symptoms. (Pale strip and looks like fungal growth, some have got white bulge around their eyes) the pale stripe gets worse until the fish dies.

I really need help if anyone knows what is going on I’ve lost over 6 fish in three days!!!

The first photo is showing the pale band around the body. Second and third are of the white buldge around eyes aswell as her tail region.

The problem is likely, Columnaris, a deadly bacteria.
If you have a QT tank, remove any obviously infected fish asap and either treat the disease with antibiotics or euthanize.
Columnaris is nearly impossible to cure. Don't treat your display tank with antibiotics. It will likely wreck havoc on your aquarium environment.

I removed all visibly infected fish from my 10 and transferred them to the Hospital tank. But each day a new fish in my 10 starts to show signs. And what antibiotic do you recommend for this?

The most recommended antibiotics are Kanaplex & Furan 2.

I am going through a bout of columaris now that killed one of my betta. I found this thread that can be found on this forum.
