Nesaea pedilica?

Iím not sure which forum this query belongs in, but here goes. I picked up these plants about a month and a half ago. The redder of the two seems to be growing fast and doing very well, but I canít figure out what it is. We were thinking Ludwigia when I got it, but I canít match it to a species. I think the greener plant is Nesaea pedilica (sp?) but Iím not exactly sure. I may still be looking at a transplant shock, but this plant is growing slower than Iíd expect from a stem plant and the lower leaves are showing black discoloration. Also, it hasnít reached much above 6Ē but the top/new leaves are coming in with an orange flush. Iím pretty confident with the water column parameters and light level, but my sustrate is long, long overdue for a change-out. So, basically:

1- What is the red plant?
2- If the green plant is N. pedilica, what are itís substrate preferences? Is it generally a forground or midground plant? Is the black a sign of stress? (seems to be getting better, but Iím still curious)

Tank parameters:
50gal, heavily planted
Half tank under 150W HQI MH pendant, Half under 30W PC
(unknown plants on the bright side, fairly close to light source.)
pH: 6.8-7.0, day/night flux due to CO2
Hardness: 6.8dKH, 7dGH
NO3: 2-7ppm (added as KNO3)
Also fertilized with K2SO4, and Plantex CSM+B, Mg, Fe, and Flourite root tabs.
