Copperband: Fungal or Bacterial?

[FlyPenFly]

Was in my QT for about a week eating LRS and live worms. This morning not really taking any food and showing white discoloration at the top area.


Treat with NFG?

Also have Metroplex, Kanaplex, copper, and focus.

It's hard to tell for 100% certain based on those pics. Is the area fuzzy looking or just discolored.

I use NFG plus Metroplex on butterflies whenever I can because they are notorious for bacterial infections.
