Excellent for beginners. Extremely hardy plant. Does well in just about any setup.
I have the "bronze" variety (although, I think it could be the "red" one). I planted it in a 20L tank with 1.8wpg light, no ferts, no CO2 (not even Excel). They just grow and grow and grow! Very pretty color, as well.
I've harvested some for my 75g tank with 2.44wpg, EI ferts and injected CO2, and it's growing very well there, too.
It does appear to grow taller, more upright in lower light while it stays lower, more horizontal in bright light. It also seems to have more color in lower light, but that may be due to the bottom of the leaves not showing as much in high light.
I disagree with the person who said it is a difficult plant to transplant. This is a really tough plant that will thrive where most other plants refuse to grow. If you have to transplant it, trim the roots to about 2" and plant. I have not had them show any ill effects from this. They regrow their roots quickly and continue on as if nothing ever happened. Sometimes one or two of the bottom leaves will melt, but that's it.
