Well that center plant in the second pic with the long stem is a Dracanea species sold at Petsmart as White Ribbon. Non Aquatic species that would do fine in a terranium/vivarium/paludarium. Is there a way you can take the plants out of the tank and lay the out so we can id them better? What is your lighting? How many watts? And you also got some duckweed....good luck getting rid of that.
