E parvulus is the shorter grass, E. acicularis is taller and often sold as
dwarf hairgrass. E vivipara is a ratty branching type that use to be quite
common.

It's somewhat picky to start but then really picks up once the roots
establish(1-3 weeks). Likes cooler water, moderate light(warmer colors did
better), lots of CO2, clean water etc. Needs vacuumed and/or combed to keep
looking nice or pruning by sod piece removal etc. Shrimps, snails work best
for cleaning.
