Suggest me a grasslike plant

I do think that there are larger species or varieties of sags so maybe you didn't get the dwarfs

Pygmy chain swords are probably the best fit for your description.

The Dwarf Sag is a single species, S. subulata. Of course, what also gets sold as dwarf sag, who knows. The true one generally stays at around 4".

But a lot of other sag species are commonly sold as pond plants and are found in the southern US. As I said, could have been mislabeled.
