Rotala Rotundifolia slow growth rate
I currently have a 20gal high tech tank that is pretty heavily planted. It has been fully planted since the end of March.
The planting is as follows:
Rotala sp. Green
Anubias Nana Petite
Cryptocoryne "Green gecko"
I am having great success with every plant except the rotundifolia. I have had to trim all the stems several times as they reach the top of the tank, but the rotundifolia grows soooo slowly. I had these in a planted tank a few years ago and they took of like weeds. I even get a consistent 1-2 new leaves on all 12 anubias plants every week.
Does anyone have any idea what is going on? It just seems odd that only one of three rotala species are exhibiting this behavior.
Thanks for any help that anyone can provide!
