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.

Rotala Bangladesh

Rotala sp.

plantfreshwater

Compact Rotala with thick stems and rounded leaves that blush deep red under intense light. Rarely grows tall — ideal for creating low, dense red accent patches in aquascapes.

Rotala Blood Red

Rotala sp.

plantfreshwater

One of the most intensely coloured Rotala varieties available, producing deep blood-red to crimson stems and leaves that stand out dramatically in any scape. Requires the highest light levels and CO₂ of any commonly kept Rotala, along with careful nutrient management. Under suboptimal conditions the colour fades to dull orange or pink. Grown well, it creates an arresting, almost unreal red that elevates competition-level scapes.
