Hygrophila Pinnatifida vs Dwarf Hygrophila
How the Hygrophila Pinnatifida and Dwarf Hygrophila compare on care, size, water and temperament, and which plant suits your tank.
By Mike ElmiraUpdated
TL;DR, Hygrophila Pinnatifida vs Dwarf Hygrophila
The Hygrophila Pinnatifida and the Dwarf Hygrophila are close cousins, both in the Hygrophila group, so at a glance they ask for a lot of the same things. Both are happy somewhere around 22 to 28 °C and pH 6 to 7.5, so a single tank can suit either one. The Dwarf Hygrophila is the more forgiving of the two, which matters if this is an early tank, while the Hygrophila Pinnatifida rewards a bit more attention. In a low-tech, low-light setup the Dwarf Hygrophila is the safer bet; the other really wants brighter light to look its best.
