It's been really bad
I lose my 5 year old purple tang
Naso tang
Regal angel
Pair of my black and white clown
Lawnmover blenny
Copperband butterfly
While the blue tang was inside the acclimation box for 2 days my bully blue tang stress it so much it develop a ick even though it was on copper treatment tank for 2 weeks and the previous owner claims it never have ick since he got it
The smaller blue tang now is doing well but the damage is done.
