What stem plants grow like weed in your tank
I have a medium light high tech tank and tried a number of stem plants, all rated easy to very easy. So far, the only stem that grows like weed for me is hygrophila polysperma sunset. I tried rotala rotundifolia, Ludwigian repens, mermaid weed, limophilia aromatica, and a few other species of the said genus, and none grow fast, often developed weak root and bare lower stems. Whatís your experience.
