I have this plant in my tank its a sort of dark green with long thinner type of leaves, it has grown a shoot the past couple days that looked rather like a seed head slightly purple in colour at the top, its now shot up a couple of inches since last night and is out of the water, what should I do? Should I cut it off or see what it does because it kinda looks like it might just keep growing and its nearly touching the lid?! At least its a good sign if its growing!
