| Hygrophila polysperma -pink- is normally an undemanding plant. But if you want deep-pink leaves you must provide intensive light. The distinctive colouring of the light leaf ribs is probably caused by a virus which prevents chlorophyll from being produced in the cells around the leaf ribs, making them white. However, this virus does not affect other plants in the aquarium. |
