Large Queen Angel hasn't eaten in 10 days

[zs2000]

I've had this Angel for 4 years and never a problem. Some months ago I moved tanks and the new tank had an ich outbreak, So the water was treated with copper(This may be unrelated). All fish in the tank recovered and are now eating without any problems. But since 10 days ago my queen angel hasn't eaten anything. Tried seaweed, store brand, home made food but nothing will get them to eat. Maybe 2 weeks ago there was a strange problem with their mouth looking like it was stuck open, it only lasted a few days and they look normal again. I'm worried now they are going to starve themselves to death. The salinity is 1.019 and water changes are frequent. There are no other angels of course, just a Sailfin tang clowns and a wrasse. What can I try to make them eat again?

So the angel is still in a display, correct? What size tank?
Is there still copper in the water?

While they can thrive in 1.019, have you tried jumping to 1.022?
Has there been a change in temperature and/or salinity?
Is fish breathing normal or labored?
Any video you can provide of fish under white lighting and at least 20 seconds in length?

While these fish are known to occasionally go on hunger strikes, due to stress, copper at times can play a role?
What copper product did you use and how long did you treat and what therapeutic level?
Also chech dkh as for some reason with these large angels, low dkh affects their eating abilities

Can you post a video of the angel and the tank?

Here is a link to an article I wrote on fish anorexia:

Chronic Anorexia in Aquarium Fishes

Don't fall into the trap of assuming the fish will begin feeding when it gets hungry enough, or conclude it must be eating something, just not when you are watching.
