What plant is this?

Does anyone have an idea what type of plant this is, especially its name? Hope the pictures are clear enough to identify it.

Hygrophila polysperma I believe

[Aiglos]

I'll verify that.

specifically 'Rosanervig'

You can tell it is Tropic Sunset due to the white veins between the leaves.
