Need help with clown fish selection

[SC50964]

Hi I'm new to this. Seeking advice from you guys. I have a 180 gallon FOWLR system. I currently have queen angel, emperor angel, flagfin angel, blue tang, harlequin tusk, mystery wrasse, a fairy wrasse, and two blue cromis. I have a pair of black ice clowns in my 90 gallon QT. I'm thinking about adding either a pair of frostbite or a pair phantom. Pls let me know your thoughts. Thanks.
