I got this gold rim tang last Sunday and put him in QT. He was showing signs of ick so I started dosing copper and reached a therapeutic level by Tuesday. He was eating nori and seemed to be doing well until tonight I found him hiding and breathing heavily. He does swim lethargically and dazed. I did a 10g wc on the 20g tank and started carbon. I have 2 ammonia badges on the tank reading safe. I just preformed a FW dip but I don’t think I saw any flukes and the condition doesn’t appear to have changed now back in the tank. Should I remove the carbon and start prazi now or is there another course of action I should take or none at all? TIA!
