Oh ok. Beware the firefish if you dont have a top on your tank, they jump out.
I would suggest A Royal Gramma (purple and yellow) a pair of tank raised ocellaris clowns (orange and white-hearty and inexpensive) a blue-green chromis (very inexpensive), and then later on if you arent doing corals, a dwarf angel. If you dont mind waiting till the tank is WELL established, a bi-color dwarf angel may be worth a try as it could be the showpiece of your 46G. They are a bit harder to keep however so if you are i in a hurry youll need to select a flame angel or coral beauty instead. Dont attempt a yellow tang/any tangs/ or any rabbit fish for that size tank.
The last fish to go in after all the other are in....could be a mandarin. I recommend a refugium and a healthy pop population set up first however. The CPR in tank refugiums wont break the bank and you can actually order the pods in a bottle now days online or even at the local fish store.
A tad bit more color could come in with a nice looking shrimp like the blood red, although i have never had too much luck keeping shrimp alive for some reason (not sure if there was a hitch hiker in my old tank that was killing them that i never identified or if they just got sucked up in my power heads (those maxi 1200s seem dangerous).
Good luck!
