Aggressive Bicolor Pseudochromis HELP

[sebipp]

I have a bicolor Pseudochromis which is going after my sandsifter goby. I also recently added a bangai cardinal fish which was perfectly healthy until the BP got to him. I have had a Coral Beuty for alsmost six months before the BP and always swam around, now he does nothing but hide. What is the best, stress free, way to catch the pseudochromis?

get rid of your other fish and put in a undulated trigger then we redefine what is agressive lol
no just put a little bit of food at the very top of the tank and scoop him out
