This type looks like Rotala Rotundifolia, but it has a darker red tone with leaf margins rolled outwards. It’s difficult to cultivate, particularly in low-tech tanks.
Rotala Macrandra ‘Mini Type 4 Green

Rotala Macrandra ‘Tiny Type 4 Red
This variety has the same characteristics as the mini type 4 green. Still, it has a deep red hue and demands high illumination, nutrient-rich substrate, and enough water column fertilization.
Rotala Macrandra ‘Mini Type 2’
Its unusual, curled leaf edges are primarily green with pink and orange highlights. This kind, like other minis, is difficult to cultivate and sustain in the long run.

Aquarium light and the intensity depend on the type of plants selected for the new aquascape. Usually, 6–8 hours of aquarium light are enough for a planted tank. You can add a CO2 system to boost the growth of the plants, but it is not a mandatory requirement.
