Excellent! I have chosen this thread to be on our front page, so everyone coming to the site will see it.
The reddish plant is a
Ludwigia, though I think it's likely a species like
L. peploides or
L. adscendens that aren't really suitable for aquariums.
The narrow leaved green plant looks like something from the Rubiaceae family, but I can't say with more certainty without a closeup, especially of the nodes. If you please...
