A fun livebearer to try out is Heterandia Formosa (dwarf livebearer) as it stays very small and can be very fun in a larger tank like that. It is a native, but can be found at a few places online for sale. Some of the Goodeids are also very cool and with most being endangered in the wild is something you can be proud of housing and are often sought after in the hobby. Try googleing Zoogoneticus tequila or Characadon Lateralis
