Hi all,
If it is Ophiopogon it will have very stiff leaves, if it is Sagittaria or similar it will be lot more floppy.

The grassy, stiff leaved plant in your second tank looks like it might be Ophiogon which isn't aquatic.This are my first and second aquaecapes. the first one is in a Fluval Flex 9 gallons, no CO2.
The second one is in a 4.2 gallon cube. Low tech too but has a good light.
I don’t know the names of the plants but you can see they are growing great!
