I have a 7 inch established sailfin tang. About 3 weeks ago, I bought a 3 inch yellow tang and added it. The first night, the sailfin was a real jerk and beat him up. The next morning morning, there was no agression. Maybe every now and then he'd rush the yellow, but not often and just once at a time. The yellow quickly recovered and began eating, but a few days ago he stopped eating and died today, presumably because of the sailfin. I have 3 more tangs coming in on friday. What's my best course of action to get them established and not dead? I have a small acclimation box. I'm trying to find a mirror to put in the tank with the sailfin. I can possibly put him in the refugium as a last resort? I can put pvc in the tank or something? I really need advice, I cant go through this again

The sailfin will probably be aggressive no matter what, it's established and will likely be territorial. Are they going through quarantine before being added? If there was no more obvious signs that the sailfin killed it something else could be going on. What other tangs do you have coming?

I strongly suggest doing so. That much new tang with no quarantine and lots of stress is a recipe for disaster. What size system is this?

In my experience it is a lot worse adding one fish rather than many. When it is just one fish the aggressor can really target that one and beat him to death. When there is 2 or more the aggression is typically divided up and usually lasts a shorter time. This has been my experience with naso, purple, powder blue, and clown tangs. Of course you have to provide enough swimming and hiding room, and do need to overfeed for the first week.
