What fish can be mixed with a betta?

have my Betta living happily with several Guppies, 2 African Frogs, 2 cat fish, 2 plecos and a Platy...I will be getting more Platy as they prefer to school.
My mother has her Betta with a school of neon tetras, cat fish, plecos, African frogs and Guppies, all with out any problems.
I understand that as long as you do not add a fish with long showy fins, which the Betta may interpret as competition, you will fine. Here a few sites on compatibility which may help you... http://www.timstropicals.com/Compatibility/NameResults.asp http://nz.,
