Good focus fish for a nano

[ThisGuy12]

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.

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.

you should see the lemon citron goby.. I really like that guy. Out of the 30+ fish I have, he's by far my favorite.

They swim and just sit and stare at you, but they are pretty personable. Mine will eat out of my hand!

Thanks for your suggestions everyone.

As I already have quite a few fish with yellow, purple, and black, I wanted something that had a nice contrast with the other fish and the corals (most of which are red/pink).

Over the weekend I found Stu, a blue sapphire (aka springer's) damsel. He is a beautiful electric blue with black markings. The picture doesn't even come close.

I chose one of the smallest of the bunch, as my research shows that younger springer's damsels are much more peaceful, while springers as a whole (adults too) are one of the most peaceful of the damsels.

So far there have been no issues with introduction with the other tank mates (unfortunately I hadn't planned to get Stu so early, just happened to find myself in the NE after missing my turn off Deerfoot.... and my QT wasn't set up, with the pump and heater being broken when I tried.) He set up shop around my monti caps, and is small enough that he hides between them and the rock when he is startled.

So far he eats like a pig, and loves to swim around the column.
