Tentative fish stocking list

[ponokareefer]

6 line wrasse's can turn into terrors. I had considered getting one but most people that have had them said they turned very aggressive.
Spotted(Pajama) Cardinals do better in pairs. Mine are a breeding pair. They will tolerate more than 2, but don't get along.
Bangaii's are fun in a pair as well. I'm not sure if they get along with other cardinal's though, and you definitely want to make sure you get a pair.
As others have pointed out, I would avoid a mandarin unless you are going to feed it their specific food.
For firefish, I've always read that you either get a pair that is already paired up, or stick with one. You're tank is covered so you are good that way.
The rest of your list looks good. A fairy or flasher wrasse will do fine with your current selection. There a tonne to choose from as well.
