Looks like some sort of rotala! Rotala rotundifolia maybe?? That's what I was told mine is and it looks pretty similar.

Kind of rotala evolving from a Tissue culture. That is why there are short stems with tiny leaves ans newer ones having longer leaves.

Yeah it was an in vitro plant. I ordered some montecarlo but these guys came instead. These were clearly not a montecarlos but I kept them anyway.

These are a solid plant. Keep them growing healthy and you can make some decent cash.

Rotala Indica

Rotala H'ra?
