I got it ages ago without a label and has just survived in a low light set-up. Put it into my main tank and has more than doubled in size in a month.
It only sits about 5 cm high with the individual leaves being about 4cms long
I was uncertain myself about Wendtii due to the fact that the leaves didn't appear "crinkly" enough but reading the description of size, etc it probably is. That was why I was wondering if it could have been Parva.
