I've noticed over my years of having planted aquariums that I can never get java fern or swords to grow. Not to toot my own horn, but I'd say my planted tank looks pretty darn good and lush, but the thing that always fails me is those two. The leaves just slowly die back until I'm left with maybe a few tiny, inch long leaves and the rhizome. I've always been told they're easy plants that tolerate close to anything, but they just won't work for me. Anyone else have the same issue?
