Ethical question: What would you do? UPDATE: HOLY COW I CAUGHT HIM ON THE 1ST TRY!

Down the road if you want to try the same fish combination again, you can maybe try this.

Get rid of that large King Angel and buy the smallest one you can find, perhaps 3". But before doing that, think of all the other angels that you would like to add and do that first. Starting with the smallest or most timid ones. Let them settle in for a couple months and then add your meaniest fish, King angel. This strategy worked for me. I have had two Emperors, one regal, one blueface , one majestic, one asfur, and 3 flames. All in a tank half your size. And this was just angels we're talking about, the tank also had 9 tangs and some other fishes. Angels treat each other much better when crowded. The more space they have the more territorial they become, your tank is a perfect example.

IME, this method worked for me as the fish were still young, between 4-6". I don't know how they would behave once they all reach 6-7" plus. My guess is that the agression of the largest emperor would rule the tank and if it pairs up with the smaller one, who knows how it would turn out. I had this combination of fish for a year and changed it over to a reef. I currently still have a pair of Emperor and one Regal happily swimming together. Fingers cross for the Emperors to pair up.

All that aside, we're talking about the King Angel here, would think very hard before mixing it with other angels.
