I have a betta sorority in a 20H, and in this sorority I have a young guppy pair (male & female). They have been accepted by the betta girls and yes, the male got nipped a little at first but his beautiful tail has healed just fine.
Guppies are very beautiful fish in their own right, but their lifespans are about half of a betta's (2 1/2 years compared to 5 years for a betta).
I have a female betta in a 5 gallon tank, and at almost three inches long, there really isn't enough room for another fish. I did terribly overstock my five gallon originally - before I knew better and before my fish GREW - and my betta got popeye as a result.
I rehomes the other fish from the five gallon and my betta recovered - but now is blind in one eye. So, I wouldn't reccomend cramming too many fish into one tank. What looks roomy to us can be biologically crowded & toxic!
20H: 2 Cory Catfish, One very mellow Cambodian female Betta, Two Golden Veil Angelfish (male and female)
