The first is the stem plant in the lower center of this photo that also pokes up on the left from behind the rock. The stem easily fractures into shorter pieces but stays put and grows well with CO2 and EI dosing.
This second has a poor photo, sorry. It has a single stem and multi-lobed leaves similar to H. difformis in look. It is NOT wisteria though; the leaves are broader and they all come from the central stem. I am asking about the blurred plant beneath the endler and behind the Cyperus helferi leaf.
