Species description
This red-leafed variant of Blyxa aubertii originates from the warm, tropical zones of Southeast Asia, northern Australia, and East Africa. In the wild, it grows strictly submerged in calm or slow-moving freshwaters, such as shallow pools, marshes, rice fields, and sunlit stream banks. It thrives in muddy, nutrient-rich substrates where direct sunlight can reach its leaves, triggering the production of red pigments. Belonging to the family Hydrocharitaceae and the genus Blyxa, the "Red" cultivar is a natural genetic selection known for producing anthocyanin pigments under high light. Unlike other Blyxa species which have short stems, Blyxa aubertii grows strictly as a stemless rosette.
Care, breeding and tankmates
Prefers soft to moderately hard water with a KH range of 0 to 14 dKH and a pH of 5.0 to 7.5. It is sensitive to high organic waste and water column pollutants, requiring efficient filtration and regular water changes. The suitable temperature range is 16°C to 32°C. Iron and light deficiencies are the primary risks, causing the leaves to turn pale and the crown to decay. The leaves are very delicate and break easily if disturbed.
Geographic Origin and Distribution
This species originates from: Southeast Asia, Northern Australia, East Africa.

- Midground, Background
It is a striking centerpiece or midground accent plant designed to draw the eye. Because it requires intense light to color up, it must be placed in a prominent, unshaded area. It looks best when contrasted against bright green plants.
It shares the same large, grassy rosette form as standard Blyxa aubertii. Under strong light, its leaves develop stunning shades of orange, red, and maroon. The intensity of the color is directly correlated to light intensity.
Its growth rate is generally moderate, slightly slower than the standard green variety. With a rich substrate and high CO2, it forms a dense clump over time. Patience is required for it to reach its full potential.
The "Red" variant of Blyxa aubertii is highly dependent on an iron-rich, nutrient-dense substrate to bring out its striking burgundy and bronze coloration. A deep bed of premium aqua soil is strictly necessary to house its massive root ball and fulfill its intense metabolic demands. Without substantial root-level fertilization, the plant will struggle to grow and its foliage will revert to a washed-out green.
A comprehensive liquid dosing schedule is required, with a strong emphasis on iron and trace elements. Some aquarists find that slight nitrate limitation can further enhance the redness. Balanced nutrients are essential for overall health.
A premium, highly fertile substrate is absolutely essential for this plant. Heavy root feeding with iron-rich root tabs will significantly improve its color. It draws the majority of its essential nutrients through its roots.
Trim by selectively removing older, faded, or damaged leaves from the outer edges of the rosette. Never top the plant by cutting the leaves in half. Removing old growth encourages vibrant new leaves.
Propagation is done by dividing the basal offsets that occasionally develop around the main crown. This process requires patience, as the plant does not propagate rapidly. Ensure the offsets are large enough before separating them.
This is a demanding plant that quickly loses its color if conditions are less than ideal. It is highly susceptible to shading and will melt if light levels drop too low. It also requires very stable water chemistry.
Its primary role is to serve as a dramatic, colorful focal point in high-tech aquascapes. It provides incredible contrast against green plants and dark hardscape materials. It is highly prized by advanced aquascapers.
