Female Lyretail acting strange

[NattieReef]

This morning one of my female Lyretail was acting just fine, then about 3 hours later she’s swimming to the top sticking her head out, then laying on her side on the bottom. All other fish are acting fine.

Background- 20 days ago I purchased 4 Lyretail 3F 1M, one yellow Coris Wrasse and a small watchman goby. I put them all in my QT tank, treated with copper at 2.0 then slowly brought it to 2.25 and then 2.4. The QT is 20 gallons so I do a 100% water change every 3 days. After 14 days I stopped the copper and started prazi. I have done 2 water changes (6 days) of prazi. The last water change I did (3 days ago) I did 50% DT water and 50% freshly made salt water. I wanted to start acclimating them to DT water. Today one of the females is looking pale and lethargic. I see no signs of ich or velvet. She’s not breathing rapidly as far as I can tell. No other fish are acting strange, just this one. I’m uncertain what to do. I just did another 100% water change, I did not add any copper or prazi to this water. Any advice is appreciated. I’ll add two pictures of the fish. If any additional info is needed, let me know.

ASSURE AMMONIA IS NOT ELEVATED. Was water temperature the same as previous water and was salt level higher than the previous content?

Welcome to Reef2Reef!

The other three anthias are swimming and eating fine?

Did the tank have good aeration when you dosed the prazi?
No signs of aggression from the other fish towards this one?
