My first Fish copper Qt treatment

[MichaelB]

Wrasse, some angels , anthias, some tangs, butterflies don’t do well in copper especially over 2.0. They die. Copper isn’t as good as YouTube people make it seem.

Yes seriously I make it through this headache. I won't be randomly tossing in fish into existing tanks any more. I wouldn't wanna experience this tank wide issue again.

It would be far easier treating 1-2 new fish than a full tank of them.
