I have about 5 narrow chain sword planted by the foreground of the tank. 4 of them have runners already (not sure why the 5th one does not have any runners). Unfortunately, I have 2 runners with the tip end nipped by my fish. Possibility by the Red Eye Tetras. I had already covered some of the runners with a clipped off spring water bottle tops. Would the nipped end of the runners regrow? Or I just have to wait until the baby plants to mature first before seeing more runners?
