Ambient light from a room for feeding and remember to feed food that has been soaked with garlic and selcon to help with the fish's metabolism and immune system the copper will most likely affect their livers any tangs or angle fish their stomachs bacteria will be killed so they may not do so well.
I wish you all the best with this as you have to be dedicated to help these fish FW dips every day helps a bit. lower the salinity and raise the temp. Thats all I can offer you the way of help, other than if they are not going to make it clove oil will put them down. I would dip them first and find out if they have flukes but that would be the worst case of flukes I have seen in a long time.

Agreed about the FW dips. It wasn't until close to the 2nd week of treatment and I got brave enough to do FW dips that I noticed huge improvements with the fish's ability to breathe better.
