What makes a better foreground plant? riccia fluitans or Hemianthus callitrichoides, what are their pros and cons?
You are the best...i had no idea haha. But after close examination, i can conclude that i have the Japanese variety. I just thought that riccia should be flat and leafy like but i am glad that you showed me this. i went ahead and washed all the riccia and bought some mosquito nets and wrap them around rocks and submerged it. But thanks alot darkblade i would have never knew about the different types. Here are a few pictures.Different growth conditions can lead to different appearances of Riccia, I believe. If it's thicker, it could be due to more nutrients, more light, and more CO2.
In addition, there are different Riccia varieties too, so that might be another thing you are seeing.
Edit: Tropica has a good article on this:
