These val's were 1 4" tall val about 8 months ago, and now they are everywhere, runners all over the whole tank and have to be trimmed because they get 30-40" long and leaves everywhere. I only started with 1 tiny plant.
I have had them before, but been a while. I have had either good luck or bad luck. I am hoping for some really good luck this time lol.
I love it when the get 36+ inches, float at the top, blocking some light, flowing in the currents, making the light beams going in the tank breath taking. Better stop, almost sounded like I was writing a book called 50 shades of planted tanks lol
