150 would be too small for any one of those fish, sorry. do you want a nice planted tank? that way you can get some really nice colors out of a vast assortment of fish. you could get aussie rainbows schooling around some nice vegetation... or a school of blood thirsty exodon paradox, (which is my suggestion to any and all that want color/activity/less upkeep than piranha with similar results).
you could go with an asian predator tank with various cyprinids like bala sharks and apollo sharks. throw some gouramis up top with a few dats to patrol the middle, and you have yourself a nice asian biotope aquarium.
personally, i like planted tanks with a high level of activity, which you would get from all of these options. and i do like the oddball african tanks, you could get some rare fish with that idea.
