hair grass is Lilaoepsis brasiliensis, called Microsword
it is an hard plant but he suffered some BBA (it started on it). Its colour turned darker and it stopped to grow.
Now it is growing again. I'll make better photos soon.
Riccia is going well, it grows in crazy way and soon i will need to make it grab again on the rocks because it is near to float up
Postemon helderi is going good. It is a really hard plant and grow fast but it needed more space than i've reserved to it.
It could suffer from BBA attacks too.
Hemianthus and glosso (i made a mixed carpet) seems to grow again, but they are difficult because they needed more space too
