I had 2 of those bleheri swords in my lil 25g that grew and grew and grew. I transferred them to the new tank.......the roots were huge! I used them to help cycle the new tank. I pulled them out when I planted the new plants. I put in an ozelot sword, its only a few leaves, (only one) I read it doesn't get so big, 9 inches or so max (I hope). I planted hygrophilia around it. When it gets bigger, I'll pull out the hygro, but I'm hoping this plant takes awhile to get that large. I luv the swords, but what hogs! Is there such thing as a small one?
