Sick fish in big tank

[Cohenjl13]

I have a 110g freshwater planted tank and two of my red nose rummies have fungus growing on them, what is the best way to treat the whole tank since i cant catch them and/or best medicine to use.

Just a thought but is it fungus for sure (where is it located eg wounds or mouth, etc). Generally I get one with fungus (have managed to get a couple) but bacterial infections I find will more easily spread across schools.

It s a large white poof on its tail, he looks like hes wearing a cotton ball. The other one has been ill for a while looks like ick, but it has spread or made gotten worse...

For the most part fungus only grows on damaged tissue,so if there isn't an injury then I would try to re diagnose..
AS for treating a large tank ,more meds and water changes..
I have treated my 180 a couple times and it is why I have a 1gallon jug of Rid Ich Plus !
If you don't have sensitive fish then go full strength with meds day one and possibly increase the amount day 2.Large tanks can contain a lot more organics in it and they tend to neutralize/reduce the effects of meds.
Big water change before any meds.
Here is a couple links I post often on columnaris just so you can check.
