only ??? is how hard is it to keep going? low light bright light? I am a returning newbie, past experiences w/planted has been 50/50 successful. Currently setting up a 37 gal. tank. need to get substrate, and I am ready to roll.
I absolutely love this plant. Fair warning that one must have control over their tanks for this to thrive otherwise it has the ability to be invasive like duckweed. This is one plant that can totall change shape with co2 or emerged within days.... Awesome stuff.
