ScaperGirl Posted February 23 Share Posted February 23 Hey everyone - I bought some new neon tetras from my LFS about a week ago and they seemed to be settling in well. But today I noticed one of them has a bit of a gray patch on its spine. It’s not fluffy or anything. Any ideas? I have moved the little one to a separate QT tank for now. The tank is a 22G long and cycled (5 nitrate, 0 nitrite and 0 ammonia, pH ~7.4, temp 75F, filtered, 25-50% water change every other day for 1st week). Only other fish are some false julii Cory’s I bought the same day. Link to comment Share on other sites More sharing options...
Colu Posted February 23 Share Posted February 23 Light patches like this can be caused by columnaris that's a gram negative bacterial infections that spreads more rapidly at higher temperatures and can kill in 24hr to 7days for the cold water stains the most effective treatment is a combination of kanaplex and jungal fungus clear fizz tabs containing nitrofurazone following this treatment plan Link to comment Share on other sites More sharing options...
