I am horrible at keeping plants so, I decided to give keeping Duckweed in my five-gallon nano aquarium a try. I put algae wafers in my tank with the hopes it would help the tank cycle and today I added approximately 100 Live Duckweed Plants (Lemna Minor) to my aquarium. I am trying to prepare it for a few White Cloud Minnows and Red Cherry Shrimp. I have a sponge filter in this tank. What tips and advice can you please give me on how to grow Duckweed?
