Rotala rotundifolia from South-East Asia has long, thin leaves and 15-30 long stems, 2-3 cm wide including the leaves. Unlike other Rotala species it is relatively undemanding, although it needs good light to produce red leaves. It forms side shoots willingly, becoming compact and bushy. This also means that it is hard for light to reach the lower leaves, so the plant should be pruned frequently

Ludwigia repens is one of the easiest red plants to grow in the aquarium, being able to grow in even lower light conditions. It also makes an excellent candidate for moderately lit, non-CO2 aquaria.
