I'm always amazed at how robust some of these creatures are. I've medicated
tanks with copper that have had misc live rock w/ critters (mainly as a food
source for sick tangs/angels) and noticed many of these critters come thru
the medication just fine. Always a little confused about this since it is
suppose to kill everything.
Traditional advice is once a tank is treated with copper it can never house
inverts again. I've heard people dismiss this as rubbish (run carbon for 6
months are you are fine) and my personal experience above "seems" to support
it. If I had a tank treated with copper at some point in the past and I
want to introduce crabs or snails would that be O.K. ? Has anyone had any
experience with this ? Perhaps some critters can take it and other can't ?

Not only will they not hurt any fish, they are very beneficial to your
system. They are scavengers and help keep the tank clean of excess foods,
fish waste and algae. You are lucky to have a healthy copepod population,
especially if you medicated the tank. One thing to think about is an
explosion of copepods can signify excess foods in the tank. You may want to
consider cutting your feedings down a bit when you get fish back in the tank
(depending on how much you were feeding).
FWIW/IMO
