A quick question about stocking

[kluivertfan2]

I've recently aquired a 12g JBJ Nano and was wondering which fish to put in it.
As of now there are three fish and a few inverts I have in mind, but was wondering which way to procede. I'm not looking to keep any advanced corals just the simple ones. Xenia, GSP, mushrooms and zoas, etc.
The fish I am interested in are the
Blackray Shrimp Goby, Strongobiops Nematodes and its associated Pistol shrimp, A Randalli
Royal Gramma
and
Clownfish (perc or false perc, no prefernce between the two)

Would I be able to keep all three fish in there, just two, or just one?

I have a clown in my Nano and he is uber aggressive. Just something to consider.

I like the shrimp/goby combo.

Royal Gramma's are nice, maybe that and a firefish, have a peaceful tank

Just make sure your filtrations is good. Royal Grammas can get rather large and so can some clowns. For a while they will work and look good but a few years from no they will be battling for some territory.
