Ah yes, the plague of Lemna minor! Some fish, such as livebearers,
will nibble at it, but they'll nibble at other plants as well. I've heard
stories of peoples angelfish eating it as well, but this sort of depends
on the fish's personality.
Personally, I apply patience to eradicate the duckweed. Don't
throw it out though. Instead, dry it out on a pan (can be put in the
oven at a low temperature to speed this up) and then crush it up. Instant
fish food for livebearers and good greenery for other fish!
