Hum....besides this, I think also a high maintainance plant... you have to spend substancial time to maintain it:tie, trim, clean up the filter due chock by lossing riccia, clean up the floating riccia daily, etc etc etc...
Hoowever, I like to see them pearling and growing wild in the water....
Is there any other similar plant have the similar effect like riccia?
I have chrismas moss and Glossostigma and other low maintainance plants too.
But out of these 3, I still like riccia the most

also hate it the most

due to high maintainance.....
