I love this plant but have just been so frustrated with it in my big tank. What are the most effective ways of keeping it planted IN the substrate...without it coming out and floating all over, or just dieing at the base and coming apart?! It grows fine (esp in my small tank), it just won't stay still. I'm upgrading my 5G to a 10G planted tank and wish to keep this in there. I will be using eco-complete and some gravel. I would also like to bring some back to my big tank, which only has gravel. Suggestions?
