Approaches to aggression in stocking a 120

[trilinearmipmap]

OK well I decided to get two Ocellaris clowns and they have been in quarantine for a month and will go into the main tank once the live rock has cycled, any good suggestions for a next fish.

I read different things about Orchid dottybacks, some say they are peaceful, some say they will eat your cleaner shrimp, I don't know whether to get one or not.

The six-line wrasse seems to be the fish-du-jour on Reef Central the past few months, however I have read these can be aggressive and may eat the shrimp too.

I've always wanted a pair of Coral Banded shrimp but I've read about these hunting down and killing fish.

Anyway I can see the upside and downside to different kinds of fish, I'd appreciate some pointers on what to get next.
