I have some ludwiga repens that loses leaves, there's always leaves floating around the tank and always get stuck in the python. Other than that it looks very healthy. Is ludwiga repens a soft water plant? It seems to grow better in my fluorite tank with Kh 6, Gh 10, than in my onyx tank with Kh 8 and Gh 13. Changed my email program to plain text with word wrap at 60. How's that?
