So my Pygmy Chain Sword in my Natural Planted Tank is growing quite strangely. It appears as though the rhizome is growing/elongating vertically out of the substrate so that it looks like a little palm tree with the rhizome an inch tall and the leaves sprouting from the top. It is happening to 3 different plants. There are no roots growing out of the rhizome above the substrate line.
Has anyone experienced something similar? I've tried pushing it down into the substrate further but it just keeps growing taller and taller. Is the rhizome growing like crazy because of the nutrient rich soil substrate?
