I'm sure it is E.Quadricostatus as the leaves are between 10mm-15mm wide. Or
could it be a new variety of E.Quad? When I bought them, they are about 7cm tall
but when I add CO2, all my Echinodorus double in size except for E.Parviflorus
"Tropica" (ref: Dennerle). The leaves are soft and not strap-like texture. I
remember someone mentioned that they will grow tall in low light. Is this true
or just true if you have CO2 injection. I have 80W for 50g tank. The shop have
40W for their 6' tank but it is situated in a rather bright location, and do not
have CO2 injection.
