That's really beautiful! It almost reminds me of club moss. How does it make the transition between immersed/submersed? Do you have any sort of substrate or growing medium in there? I think I see some sort of soil, but I'm not sure if it's that or just a mass of Subwassertang. How much did you start out with in that little container? How big is that container? I'm all full of questions. ;-) I actually just started a Subwassertang jar on my lunch break today -- I'm always finding pieces of it floating, so wanted somewhere where I could drop them and grow them out. It's a 1.5 qt jar. They're in water, but this might be a fun experiment as well!
