Hi there,

All plants need CO2 to grow through photosynthesis. Most people feel that the pearling (due to O2 bubbles) of riccia is one of the most beautiful aquatic sights to behold. If you are looking to achieve this affect in your tank. You definitely need to have CO2, ample lighting and good nutrients.

Be warned that it will float up after a while and you have to re-tie them again ... too much effort IMO.

retieing occur once in around 2mths
not so bad lah. But the pearling effect is really great!
