Thanks for the information.
As for the lighting, well as you can see from this shot it's a bit bright in there, at least to my eyes. We've put nine plants in there and we'll see how quickly they die off, heh.
Can anybody identify this species? The leaves have fine little hairs on some of them, presumably to trap nutrients from the water. They have decent roots too. The aquatic store reckoned these could cope with hard alkaline water, low light levels, and a sandy substrate...
