This is something I've been wanting as a foreground plant. I'm new to this as well and it seems like an awesome plant. I have nothing to add to this thread, just wanted an update as people reply. LOL
Agree. When I build my big one I have forgotten parva under other cryptocorine in my schrimp tank. They were very weak and I thought that I loose them. After 8 months I have discovered that they are alive - under other plants, no fertilization, no CO2, nothing. So I replant them in my big thank and today, after few months - WOOWIt may be a slow grower, but it can be very hardy.
