we've had enormous success with water wisteria, primrose, anacharis, hornwort and java fern. any of those would be great, especially since they can all be grown either planted or free-floating, and all of our bettas LOVE having a floating canopy to swim in.
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.
