Fwiw, I recently had dark red R. macrandra crap out in 6-8 weeks
in a newly setup 10 gal (office tank) with 4.5w/gal (3 * 15 watt):
it's the only thing that hasn't grown. Generic Rotala (R. indica,
I think), Hygro, Jungle Val, two sp. Anubius, Crypt wendtii, narrow
chain sword and some Melon-sword-like sword are all doing nicely.
(Although the Val grows way too fast!)
Did my R. macrandra have *too* much light? Other ideas?
