New update:
The sword that sent out the shoot, well, the one node that was under water is now sending out roots. So I submerged the whole stem to see if I can get the rest to do the same. If I can, then I'll have several baby swords, and will put a couple in my 29G. Also, I have 2 more new shoots going out of the water, lol. Will need to prune to see if it's the same ruffled sword, or one of the others.
