Plus since being in copper shes not really ate properly...vitamin soaked foods but she doesnt seem bothered. She is still looking strong etc but not really swimming about like she used to be.
 
Copper reduces appetite in many marine fish and is counterproductive in terms of regaining health.
It also is hard on those fish with either ā€œscalesā€ or thin slime coats ( like the tang group)
He must eat well, or at least good during the treatment, Itā€™s a difficult balance.
Iā€™ve had to target feed fish before, dropping one piece at a time at the mouth.
Have zero idea on ā€œwhatā€ that mound is.
Copper is the correct treatment for marine velvet, maybe a secondary infection from an injury in QT?
It will kill fast.

Its hard to say what that is but wound does look like it opened or burst so i would definitely do antibiotics to reduce the chance of infection which might be more deadly than whats goingon originally.
