Gourami Has Fungal Infection

[Dean_89]

hi guys,
So my gourami has a white cotton fluff on its fin. From reading the pinned topics i guess its a type of fungus, just wondered what type of medication do i get? It's been there for atleast a day or two, should i just kill it and put it out of its misery because it will be a few days before i can get the medication.
Thanks for your help in advance

Don't kill it you can cure it.
For now lower temp of tank by two degrees and keep doing water changes.
You can use salt but that depends on which fish you keep. So check if you can use salt in your tank. It's a tablespoon to 5 galons.

For columnaris in the uk myxazin by waterlife.

How many gallons or litres is the tank.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.
