Ludwigia sp. "red".
Check if the stem is rotting. If it does, cut off the top and let it float until it grows roots, then replant.
It is either aclimating to your tank or hungry or both.
In either case, you need to feed your plants. LeafZone is a decent start, but do read stikies at the top of "Fertilizers" section of the forum.
