Lesser duckweed (Lemna minor)

frogmanjared

This duckweed has only one root per thallus lobe.

Nice surface covering plant for a any kind of light set-up. I started with only three little single ones. Since then its reproduced enough of it to completely cover a 55gal, 29gal, 20 gal long, and a 5gal in two months. Spreads fast but extremely hard to get rid of.

One of the best NO2-NO3 cleaner in the tank.Together with Eichornia crassipes are used in purification of water procedures.

I am possibly one of the few people who have managed to kill them off faster than they can reproduce. I believe it was the low pH of the water and that one of our bulbs was a 12000K ..Those two issues have since been addressed though. So, the duckweed is making a comeback

As a side note, if you happen to also have a separate goldfish tank, you could just dump them into that tank if you're trying to rid yourself of it from another tank . They love to gobble it all up.

Baby angel fish like to eat the root off this stuff. Good plant for helping cycle a tank.

I had the worst case of this stuff imaginable. I put two $4.99 size oranda into my 150 gallon high light/CO2 tank that was completely overrun with duckweed. I netted as much of it as I could, then let the Oranda have at it. When I returned from an out-of-town trip 2 weeks later, I had big, fat Oranda and not a spec of duckweed.

It is close to impossible to get rid of this plant. It does provide a floating carpet, very good to provide shade to other plants, but a mess if you got to catch a fish or work on the tank.

I now sell it on ebay as goldfish natural greens.. They seem to love it, so does turtles and most platties and mollies.
