you'd really need a 10 at least to get a proper school of guppies. one of my friends has a HUGE tank with at least twenty guppies and three angels, and it's amazing to watch them.
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.
