Columbian sharks actually require brackish-full marine conditions when they get older and would outgrow a 120G tank eventually.
Reed/ropefish are very cool, but I almost think that tank would be too tall, as they need to get up to the surface.
Pikes are really, really cool. There are some dwarf ones that would do very well in a 120. My friend has a gorgeous Crenicichla regani who is one of the most interactive fish I've ever met.
