Good tank mate

[mech-a-nic]

Any Ideas on a tank mate for my 55.
I have a Clown pair, and a Scope tang, cleaner, fire, and pepermint shrimp. and several BTA (1 RBTA and 3 GBTA)
I will add a Dimond Goby, looking for nother peacefull tank mate?
Thinking Flame angel maby, a firefish goby, Mandarin goby?

Any Ideas looking for color

i would go with a flame angel. it would be a nice blast of red.
or a 6 line wrasse. they can get a little aggressive tho.
i saw a 4 line wrasse the other day and i died, they are amazing too.
