Hello,

I have 9 Buenos Aires Tetras that I have had for the last 4 years. About a year ago I noticed one or two of them with what looks like columnaris. White cottony growth on the mouth. Over the last year I have on several occasions treated them with Marycn I and II together, and even have tried Fungus Guard on other occasions in case this was a true fungus. I've even tried salt treatments. In the end, the growths have not gotten worse or better. No other fish of mine that have shared a tank with them have caught this from them. My tanks are always in pristine condition, I clean weekly, use purigen, ammonia/nitrite always 0, nitrates rarely above 5-10ppm. They all have a voracious appetite, act healthy, just look ugly. Is it just that they are old geezers reaching life expectancy or is there something I am missing? Thanks!

Tried taking some pics, but still not as good as looking at it in person.
