Wanna get new fish help

Wanna add a fish this is what i got a jbj nano cube 28g hqi

live stock

1-golden marron clown
1-flame gobie
4-green chromies

but im gonna remove the green chromies,i also have a bunch of soft corals ,zoas,bubble coral,kenya cault coral ,bunch of shrooms, i have my eye on a flame angel but idk;d;d;d;d;d;d

 

First the maroons can get very aggressive(not always) and females get huge. A flame angel could work but the corals might get nipped at, the firefish might be a little passive but it could work out. Any pics of the scape?

 

Ditto on the Maroon Clown. Gets big and mean. Research nano fish (google) The Possum Wrasses are nice too. Are you saying you have a Flaming Prawn Goby???

 

I think hes referring to the firefish, but I could be mistaken.

 

Flame Angels are awesome!!!
I have one in my red sea max130d with 2 clarkiis, and an algae blenny with a hammer coral, some zoos, mushrooms and a monti cap. He usually leaves them alone.

 

thanks for the input ill paste a pic
