PLant ID and info needed

Hi Guys,
Please can you identify these plants for me.

The green one has small leaves and what seems to be little white flowers on its stalk.
The Red/purple? one has long leaves and a thin stalk.

Also , Can i plant these plants in my Discus tank? will it be safe for them and my Neons,corys ?

The tank Temp is at a constant 28.8 Degrees, The water is around ph 6.7
Will the plant be fine in the tank? will it survive and grow?

 

I've got the first one in my tank... grows fairly well. The flowers will die off. I've tried growing the red one before, no success my side. Not sure it it's a high demand plant, or non-aquatic.

 

1st one looks like Bacopa Monierri (Can't remember the exact spelling)
2nd one looks like Alternanthera Reineckii. High demand plant. High light, high nutrient requirement

 

2nd plant is non-aquatic. I was also looking into buying it but took some pics first to go do my 'homework' and found out that its non aquatic, will die of, its a marsh plant.

Thanks guy , Will the 1st one with the flowers be ok in my Discus tank?

I think ill try planting the 2nd one on one of the rocks with a bit of it above the water line.

What are marsh conditions exactly?
