I have a few Vallisneria spirallis plants in my tank and they have a habit of sending new runners out in only one direction: left. They always send new shoots that way, never to the right of the mother plant. What is up with that? They are located with a large rock behind them, but other than that there is nothing stopping them from sending runners out in any direction they please.
Also, the plants have been in the tank for about two months now, but the Valls that are in the foreground are the only ones that have sent new runners out. The plants that are located more in the mid-ground area have not send any runners out, although they have grown much taller than the others.
Any ideas what is happening? Has anyone else experienced this?
