I got into the container pond today. Just to see what was up. I did not find anything alive- except for one leech, which I threw into the lawn haha. It's the reason why I'm still reluctant to transfer any of these plants into my indoor tanks.... although the hornwort in here looks fantastic. This is the amount of it, not even spread out pretty in the water, but just set on the decking while I removed stuff to clean. It has great color and density- seems like the amount of shading greater duckweed and water lettuce plants have created is perfect for it now.
