What Should I put in this nano?

[MattR]

I originally set this up a rock anemone tank but before I load it with those I want opinions. Looking for a coral that:
comes in a wide range of colors
super easy to keep (using the aquaknight light)
Grows relatively quick
Pretty cheap

The only thing I can think of is zoas and rock anemones

Any suggestions would be great

Acans, Favia, Favites, Leptastrea

Acans are a good idea!
