I'm currently going fallow in my 260 gallon display tank for velvet. I have all my fish in a 150 gallon Rubbermaid bin being treated together with copper. I just purchased a powder blue tang, who will be undergoing quarantine separately. My question is when I finally add my fish back to the display tank, do I add all the tangs, including the new powder blue, together or should I put the powder blue in first, give him a couple of days to set up shop, and then introduce the other 6? Last time I tried adding a powder blue last, my yellow tang literally beat him to death while I was at work. My tangs have all been together for almost a year and obviously are all familiar with one another. I don't think they'll be much aggression between them when I reintroduce everybody back into the display. The powder blue is going to be the new guy regardless.
When to add new tang?

Do you have the ability to move some rockwork around while fallow? I hear some have success doing that as then all inhabitants see it as a new space. I personally have no experience in the tang world yet, just sharing other advice I have come across.

Awesome! He may even be fine now with the others if they are all freshly put into a different space. I'd just do it at a time when you can keep an eye on them for a few days. If it fails that way, then you can hurry and reseperate and put him in the "new" tank first.

Yeah I'm definitely adding my fish back on a weekend so I can watch them all. It's hard to get a good look at them while they're in a Rubbermaid but with the velvet outbreak I had to act fast. The Rubbermaid bin was the quickest, biggest, and cheapest option I had to put them all in. The powder blue will be quarantined in a 20g long.
