Looks to be Bolbitis heudelotii.

Are you sure? third from bottom, has Bolbitis in upper right corner; very different. This plant looks more moss-like and weeping.

Young Bolbitis heudelotii leaves have that weeping habit. As they mature, they become stiffer and grows more upright. Coupled with this, Amano may have placed an XLarge specimen of B. heudelotii on its side as he often does with Microsorum pteropus 'Narrow Leaf' to emphasize the temporary weeping habit. Here is another photo of B. heudelotii with upright leaves.

I swear that new gallery wasn't up there when I got to that site.

That site is attitudinal. Gallery #3, which features your photos, is not linked from Gallery #2 but a change in the site's URL will reveal it: http://www.aqua-shopping.com/cnt/gallery/index3.htm

However, it's down again. Try again later. :roll:

This depends on light intensity. If light is moderate to low, then Rotala sp. 'Green' grows vertically. Under higher light intensity, it grows horizontally and produces many side shoots/roots.
