I am in the process of quarantining my five bengai cardinals, damsel and clownfish with copper power. I am using a bare bottom fully cycled 29gallon tank with canister filter, Hob and Mp40 powerhead. I was slowly raising the copper power levels. I am also feeding them general cure + focus. I stated with 0.75 and was raising no more than 0.25 per day. At 1 ppm one of my cardinals died. Then at 1.5 my damsel died. Now I am 1.77 and one of the other cardinals started hiding in the cave and not eating properly. So, I paused any more copper from the last 2 days. It is still not eating. I don’t want the fish to die. Please let me know whether it is advisable to move him into a new uncycled tank without copper. Hopefully if he recovers, what are my options at that point of time. My ammonia and nitrate are at 0. I am using Seachem alert badge and Seneye reef monitor. Please advise how to,proceed, This is my first time quarantining fish. Kindly correct anything I might be doing wrong. Appreciate all your help.
