Foreground Plant Suggestions

[Bk718]

dwarf hairgrass, micro tenellus, glosso.

Blyxa would be good but make sure you constantly trim it since once medium size/full grown it will be 2 large for a foreground plant.

Is this already dwarf hairgrass I have in the front? Another poster thought it was. If so, I have will let it fill in.

Looks like Eleocharis acicularis or Lilaeopsis sp.
To make it spread more evenly. Pull it up and plant one or two nodes in in checker board pattern about 1/2"-1" apart.

If you want something that will stay shorter and more compact you could try Marsilea minuta.

that looks more like micro sword trimmed (Lilaeopsis brasiliensis), hairgrass has very thin blades, in your photo it seems like flat narrow blades.

Dwarf Hairgrass.

Looks nice to have some grass-looking plants.

I went ahead and ripped out some of the micro sword and "added" dwarf hair grass and some glosso.
