Oh great!!

[Edmonton Eskimo]

Well, I moved to a new house a couple weeks back and I had to move my tanks. Everything seemed okay but I lost my emperor angel to ick and now the rest of the tank has it. I have a picasso trigger,sharpnose puffer, volitans lion, lunare wrasse and a snowflake moray. The only ones I notice with ich are the picasso and the lion. What is the safest way to treat? Should I use copper or hypo? I do have a quarantine set up already. I don't want to lose anymore fish. Any help muchly appreciated.
