Good focus fish for a nano
 

I have a 30 gallon display, and am looking for a nice colourful fish that likes to swim in the water column, that isnt a clown.

I have a firefish, but she is super shy and spends most of her time near the back end of the tank or under an arch.

I also have a YWG, but he stays in his cave.

I have a royal gramma that I love. Its out swimming in the center of the tank a lot, very colorful, and easy to feed. I haven't had any issues with aggression from it, but it was one of the last fish I added. :)

If you have a good lid fairy wrasses are very nice peaceful and colourful fish, also flasher wrases

Green chromis, yellow tang (albeit the tank is small for it and it will eventually outgrow it), royal gramma, clownfish :), diamond goby, skunk or red shrimp (these are cool and glow under the right lights).

Not a fish but look at blue sea urchins they are colourful and clean your tank.

Yellow assessor, blackcap basslet, midas blenny

pygmy angels may deserve consideration; active and personable.

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.

I would recommend getting a small yellow boxfish , takes them a long time to get big. Best personality's IMO.

If you can track one down - a Flame Hawkfish. Very animated and personable. Most are peaceful and won't stray towards smaller fish/inverts. Like any other fish; it depends on its personality - every fish is different.

Boxfish are pretty neat, I really want a cowfish. But I wouldn't get one until I upgraded my tank.

Based on suggestions, I am thinking a couple blue chromis (the dark blue with black), a blue damselfish, or a black cap basslet.
