Easy small plants?

I've been working on rearranging stuff in my aquarium and after trimming away a good portion of java fern and anubias, I decided that maybe some plants on the shorter side would look better in the front. Does anyone recommend some easy maintenance plants that don't get too tall, like about three inches or so?

 

Maybe a carpeting plant/moss would work well there?

 

Dwarf hair grass and java moss would work well.

 

rosette swords are really nice attractive dark green plant. They grow around 1 inch high; maybe a wee bit more if your light isn't strong enough. wenditti bronze (crypt) will not get too large in a low tech tank.

 

Crypt parva is one of my favourite small, low-maintenance plants.

 

Dwarf Sag. Very easy. It will slowly propagate itself. I like to plant it close together in little bushes. It grows 3-4 inches.
