Rotala rotundifolia (pot)

Rotala rotundifolia is a classic aquarium plant and a staple of the hobby. It owes its popularity to its ease of cultivation and beautiful growth pattern.

R. rotundifolia is an easy red plant to grow in the aquarium. While it will grow in medium light, this plant really needs high light to show its true colors. When lit well, the plant will grow at an angle over the substrate instead of straight up. To encourage red coloration, R. rotundifolia should be kept well lit (2.5 watts per gallon or more) with no shading. Lean nitrate levels (~5 ppm), high phosphate levels (~1.5-2 ppm), and heavy iron/micronutrients dosing will help produce intense colors out of this plant. By varying these conditions, one is able to bring out various shades from pink to yellow.
