Cotton Wool Fungus

[homerhotspur]

I am fairly certain that one of my Danios has a cotton wool type fungus infection and that is what I am going to try and treat. How is this best treated?

1. 
   

Internal Bacteria Med
Specific Cotton Wool fungus Med
A salt based bath treatment
Should the fish be treated in the main tank or in an isolation tank?

thank you

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

if if it looks fluffy you will need to treat with myxazin by waterlife and pimafix.
Don't forget to increase aeration.
Good Luck.
