Quarantine Tank clown fish distress

[micgloth18]

I have just set up a 10 gallon QT tank. I have a heater a filter running on the back, all media is out except a sponge from the main tank. All the water in the QT tank is from my main tank. I have two clown fish. I true and a snowflake. They get along great and swim and hang out together all the time.
I removed the larger one, snowflake, Who was bigger when i bought her as to prevent fighting. I am not sure if they are paired or not, they still sleep in seperate areas and hang together all day.
It took me forever to catch my clown fish. I has to get a tub and put it in the tank and use a net to make her swim in it. She was super stressed as was the other fish in the tank as well.
She has been in there for a whole day and has not eatin, the fish in the MT hasn't eatin either.
Do they miss each other? should I have not seperated them?
I put her in the QT because i thought she might have ich. She has a thin white hairline on her tail and two white spots on either side of her body. I am using Cupramine. she seems to be doing well other than not eating.
I am getting some pvc to put in there to giver her a hiding place. I have painted the sides and back to help prevent stress.
If anyone has any advice I would appreciate it. I love these fish so I want to help them. I have done alot of research on QT tanks and tried my best to do everything right.
P.S. I am not sure she is the female. I saw her twitching at the other one but he is still very small so he paid no attention.
Thanks guys

You said you just set it up, and used display water, did you make sure it was cycled before you put your fish in?

Also if your clownfish actually does have ich all your fish do, they would have to be removed and treated in the QT with the DT left fallow(fishless) for ten weeks(72 days) to ensure the ich is eradicated.

This is of course IF this is ich we are dealing with.

Both fish need to be in the QT. It's really not possible for only one fish to develop ich. The main tank does need to be empty for at least 72 days. And maybe you should ease up on the copper right off the bat. Let them get used to being in there and eating again. Then treat with the copper. You should check the ammonia/nitrite daily, have fresh saltwater ready for a water change, and get a copper test kit so you know exactly what it is at. Do that and they should do fine.
