FWIW, there are apparently two different plants sold as dwarf hairgrass.. I've
had good luck with one and bad luck with the other.

I tried java moss and had no luck with it. Java ferns and cryptocorynes are
doing fine, as is pygmy chain sword (a slightly larger grass-like plant).
Anubias nana is even blooming, although it requires a bit more light than you
have.

BTW, I have hard alkaline water so that may be different than yours.
