I find chromis to be a lot like damsels, eventually always aggressive.

Also, while the orchid dottyback IS supposed to be one of the less aggressive dottybacks, it will certainly get a major hate on for your firesfish and any other conspecifics...

IMO I wouldn't chance any dottyback, wrasse or chromis/damsels in a smaller system I wanted to remain peaceful...

If the tank has a one or more mature sps in it, a couple of clown gobies always add a little colour and a lot of hilarity.

They do nip sps, but it actually seems to give larger pieces some incentive to pick up the pace ...smaller frags will suffer though.

Heres a half decent picture of my assessor...
