Multiple large angel on a reef!

[bullitr]

I started with regal angel and it did really well because I bought it from a friend so when someone is selling a emperor angel from their tank I jump on it because the chance to reek havoc on my tank i thought was less , I was deadly mistaken. This angel has very expensive taste it ate all of my high end zoa starting with my crown royal and fire and ice colony then move on to other colorful zoa but won't eat my nuisance yellow or green zoa
Anyway since the damage is done
I was wondering if I can keep 2 emperor on my 435 mixed SPS tank or maybe a queen angel
Thank you for the response
