Nano Fish Tank Eclipse

What is the perfect combination of fish for a 12 Gallon Eclipse Nano tank?

The tank will end up being a Fish only tank for now. Might add live rock in a few months after everything has been well established. I was hoping to have two Percula Clowns for sure.. What else could I put in there without things getting to crowded?

You can add a goby, anemone and a firefish.

Thre really isn’t a “perfect” combination here.
