http://www.tropica.com/productcard_1.asp?id=021

Ceratophyllum demersum is a genuine cosmopolitan found all over the globe. It has no true roots but can be planted in the bottom. In the wild it is often found rooted, with the lower leaves forming anchors. As a floating plant it provides a good hiding-place for young fish. -> C. demersum can be useful in combating algae because it consumes nutrients in the water and secretes substances that counteract algae. <- Some varieties are difficult to transport

蜈蚣草 (Egeria densa)

http://www.tropica.com/productcard_1.asp?id=058

Egeria densa is a good plant for beginners, and its rapid growth helps create a balance in the aquarium from the start. ->It can also help prevent algae because it absorbs a great number of nutrients from the water. The plant secretes antibiotic substances which can help prevent blue-green algae (a type of bacteria). <- The growth rate depends largely on the amount of light and nutrition available. Growth does not stop in unfavourable conditions, but the plant turns light in colour and the tendrils grow thin.
