Thanks Mate. I will try both Calathea and Maranta. Both are beautiful.Hi all,
You would need to keep the growing point above the water level and then the roots would spread down into the tank. I've grown <"Maranta leuconeura"> like that, they are related to Calathea spp. but a lot more forgiving.
I'll copy in @sciencefiction <"as well">.
cheers Darrel
