You may want to try hairgrass. It don't need so much care and it reproduces pretty Min by itself. All you need is some good lighting and it will grow well. Actually, you need not fill up the space at the front of you are intending to keep Corys. Corys like grazing spots and actually, this setup looks great without any plants in the empty space.

I like what you created, but I feel the sand volume is a bit thick. In the long run when the tank matures, it could be a source of hidden nutrient base that could trap and release it when you least expect it. If some parts of it turns black, you might have a problem.

Why would a thick sand substrate be a "source of hidden nutrient base that could trap and release it when you least expect it", when a thick soil substrate would not have that hazard? Is not a thick soil layer required for heavy rooting stem plants?
