I went away for 2 days, and when I got back this stalk was growing out of my brazilian sword plant. It must've grown about 6" each day because it was NOT there when I left. What is it??
probably babys, Just before I sold my sword (a regular sword, that was in a 20g, yikes) it sent off a mother shoot, the guy got a few babies with it too. I just wish my barthii would split, its a great plant, and could fit two in my 20 long.
Leave it be. When the young plant has several leaves and is developing roots, you can remove it and replant. If you let it grow out of the tank it will develop flowers.
