New Copperband damaged fin

Sorry for the loss. The fish looked healthy other than the damage so I'd say you did a good job getting it to eat which is often the hardest part. It may be tough getting the yellow to accept one. In my large tank I have 9 tangs, 4 yellows and none even paid attention to the CBBs but having multiple yellows they hang out ina group most if the time. I'm glad I have four because my 5 yo convict has decided he isn't fond if yellow aonhe has four ti pick on and they havethe tank mapped out ro get away without damage. If I had a single yellow I have no doubt the convict would kill it. Fish can act a lot different when they get to be a few years old. My convict used to be the most peaceful id them all and now he's a butt head.
An a acclimation box can be helpful. If placing the new fish in doesn't work sometimes placing the aggressor in or even removing it to the sump can help temporarily. But sometimes it just won't work. I had to use an acclimation box when I added my male CBB. I tried without it first and the female CBB pinned the male in a corner and I had to remove him. Another 30 days in observation to heal and I placed him in the tank using an acclimation box. After 9 days I took the lid off and the female swam in, introduced herself and escorted the male out of the box and they were together from then on.

Acclimation box sounds like a good idea too, read that the other fish being able to see the CBB before being able to get to it can help get them used to the new fish.. I’ve got a filefish in my sump right now that decided he liked scoly’s and acans more than aiptasia lol.

I always worry about CBB in acclimation boxes - some of the boxes are pretty small, and some have sharp edges around the ventilation holes. This can combine with them injuring their long snouts, especially if they become frightened for some reason, and poke their snouts into a hole.....

So I picked up another CBB, slightly larger this time. 2 days in a large acclimation box, let him free after and offered a clam, he didn’t pay it any attention to it.. Yellow Tang bullied a bit for the first day of of the box, then let it go. Seemed my foxface would almost intervene when they were getting tense. But no injuries occurred thankfully and he is now integrated into my tank.. he would just graze the tank at first for maybe the first week.. then he’d start nipping at the clams I put in every other day, but now. All my aiptasia is gone, he eats the clams no problem (only once or twice a week as a treat everyone gets in on it) and I’ve even noticed he eats nori off the clip with my tangs..
