Rotala

Rotala sp.

plantfreshwater

A large genus of fast-growing stem plants widely used in aquascaping for their fine, needle-like to rounded leaves and tendency to display brilliant red, pink, and orange coloration under high light and CO2 injection. Rotala species are excellent nutrient consumers that help control algae, but most species require medium to high light and CO2 supplementation to achieve their best coloration and compact growth.
