Post some additional pictures of your fish, if you can. Are you in hypo yet?
You are treating in a display tank so copper is not advisable. You can not save the fish at the cost of killing the tank. Besides, copper and hypo are equally effective, but neither works while the cysts are on the fish.
I'd like some more pictures, because Amyloodinium was being considered at the beginning. Do those dots look like dusting powder, or like pinhead sized dots? How do the gills of effected fish look, swollen, red, rapid gilling?
