Good focus fish for a nano

[tlhood]

Thanks for the ideas guys.

I like the idea of the pygmy angel, however my research suggests that 30 gallons is too small a tank, also in the case of a tang.

As my YWG and firefish are both yellow (and purple on the fire fish) I am leaning towards something more in the blueish-green colour, like the chromis or with a funky pattern like a wrasse of some sort.

My YWG is also a cranky pants so I am leaning away from most blennies, since they tend to be similar in appearance and I don't want to risk having someone get killed.
