How the Dwarf Hairgrass and Umbrella Hairgrass compare on care, size, water and temperament, and which plant suits your tank.

TL;DR, Dwarf Hairgrass vs Umbrella Hairgrass
The Dwarf Hairgrass and the Umbrella Hairgrass are close cousins, both in the Eleocharis group, so at a glance they ask for a lot of the same things. Both are happy somewhere around 20 to 28 °C and pH 6 to 7.5, so a single tank can suit either one. Neither is harder than the other to keep, so the choice comes down to look and stocking rather than skill. In a low-tech, low-light setup the Dwarf Hairgrass is the safer bet; the other really wants brighter light to look its best.
