	I have put some of what I am now calling H. Polysperma "Tropical
Sunset" in several of my tanks.  In my 180 gal tank all the leaves
have pink veins; in my 30gal tank they are white.  However, I recently
added a bunch of iron to that tank and the new leaves seem to be pink
again.  Based on this observation I would guess that you are simply low
on iron in your tank. My 180gal is running about 0.05pmm to 0.1ppm iron,
unfortunately I didn't measure the 30gal before I dump in more iron.
