Angel fish issues

[bergamer]

Wow am I having angel aggression.
I started with a flagfin who is doing fine
Next I purchased a blue angel and she started picking on the flagfin but it subsided quickly and they get along.
Then I bought a regal angel and the blue angel terrorized the regal.
So I put the regal in the sump and everything was fine.
This Sat I purchased a Singapore angel and put it in the sump with the regal and the regal terrorized the Singapore.
So I put the Singapore in the display and the blue angel went psychotic on the Singapore.
Then Sun I purchased a pearlscale butterfly. I put him in the sump to adjust and the regal went nutty on the butterfly.
So I decided to take the blue angel out and put her in the sump and put the butterfly and regal in the main display.
Then the flagfin starts fighting with the butterfly. Good thing the butterfly is a fighter and used his head spines to fight the flagfin.
Then this morning I noticed my regal and flagfin give a little chase to the Singapore.
Although the Singapore didn't seem to scared of them as he didn't really hide in the rocks.
With the blue angel out, the tank is somewhat at peace.
I plan on keeping the blue angel out for about a month and then rework the rockwork and hopefully put the blue angel back in the display.
any thoughts?
my tank is a 210g

Are they really doing serious damage to each other; or just "squabbling"?
Most angels are very territorial, but in large tank, they often work things out. Rearranging the rockwork is a good plan. Some individuals, IMO &IME, are just plain fighters and have to go. You sure putting a lot of fish in quickly; not always a good idea, but if your tank is mature, it should help minimize territorial problems. How's the regal doing? These are very hard fish to keep and if he does well, it says you're doing lots of things right...IMO.

The tank has been running for nearly 2 years.
The regal is doing fine. Atm I can only get him to eat red sea weed, which he eats 2 sheets a day. I am hoping by placing him in the main display he will get the idea to eat other foods.
The fighting is more like squabbling (although the blue angel might be a little more than squabbling).
As for adding fish, I usually don't add 2 fish at the same time, but I figured they were small and didn't add much to the bioload. I have about 100lbs of LR and another 70lbs or so in rubber main containers to add if needed (cured) and 240lbs of LS.
It was hard to pass up on an eating Singapore angel!
as for the butterfly, I have been looking for a pearlscale for sometime and to get both of these fish at the same time and coming from very healthy tanks, I just couldn't pass them up.
