Clown Bleached by Copper or Something Else?

[chandavi]

Just returned my clowns to my display tank after 30 days of copper treatment for ICH Noticed that the black one seemed bleached and had lost some of his color. Is this due to the copper? Or something else?
First photo is before treatment. Second photo is after treatment.

Most likely just lost some color due to stress. Should come back with good feeding and time.

I agree... stress plays a big role, particularly with Onyx clowns. You have a nice one BTW... where did you get it?

Thx. He (Punch) and his little friend Mango are characters. Got them at LFS (Pruess Pets in Lansing,MI)
