if you have a large enough tank with lots of plants you could (depending on personalities) keep a male with at least three females. like i said it depends on what you provide them and their temperments but it works. i owned three females and one male and they lived really peacefully
i'd never try that, no matter the tank size. they could live peacefully for years, and then all it'd take is an afternoon of stress to tear the whole thing down :(
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
