C. wendtii is a very variable plant. It could change it's appearance 2 or 3 more times on you. It will keep adjusting to the conditions in your tank, then when you do something drastic light change a light bulb, it will drop it's leaves and start over. You can't count on a wendtii to do anything that you want. I had some that were almost a foot tall in one tank. I moved some of them to another tank where I wanted them to be a foot tall, they were 4 inches tall in a month.
