Thanks guys, he's doing so much better now, swims normal, and goes after my finger when he eats, still in the 20 gal with x1 the recommended aquarium salt in it. Temp is now 85 - 86F. The white patch was gone in day one. It is beginning of day 3 not sure if it only takes 1 day to get rid of the fungus or just me being paranoid. Should I leave it in for few more days? What's the next step? Regardless, its doing all the stuff it used to do so I am happy nevertheless.
