Sometimes those boxes are the ticket. Years ago (back during the coral skeleton FO days), I had a problem when I introduced a new pygmy angel to my tank (Centropyge heraldi). The flame angel went after it like crazy and tore up it's fins, even put a scar on the side of it from the gill plate barb. I pulled the herald's angel out and treated it in QT with an antibiotic until the gash healed, then, used one of those boxes in the DT to acclimate the herald angel during reintroduction to the tank. At first, the flame wouldn't leave the box alone. Eventually, it became less and less interested. After about two weeks, I let the heralds angel go into the DT and never had any problems after that. At the time, I had a subadult blue angel, and three pygmy angels (flame, potters and heralds). They all got along after that. I was so relieved! So yeah, it's a good move, even just to be safe.
