Would anyone be able to identify these plants for me, thanks for your input!

The first plant looks like red ludwigia to me. Don't know what the other ones could be. I'm sure you'll get lots of help here though.

1) Likely Ludwigia Repens - needs more time in the tank to id
2) Dwarf Sagittaria or Pygmy Chain Sword (pretty much impossible to tell apart)
3) Blyxa Japonica

Thanks a lot for both your help!
