This plant is amazing. I went away for a few months, and when I came back it had established itself very well and grown 10 times it's original mass. It makes a lovely midground for medium sized tanks. Mine is greener than the picture but has brown accents to some of the leaves. It's growth isn't even that slow, once established. I have only topsoil and 8 watts of T12 light in a 40 gallon, no Co2, no filtration even.
i love this plant, it has grown well in both of my tanks (high light and moderate light) it grew great under both lights. but now that it is established in the moderate light it looks amazing. i don't use CO2. i did at one point use flourish tabs, and it is currently rooted in eco complete. i set it in some wood, so it looks out like it is growing out of the wood.
