Species description
This cultivar of Bucephalandra motleyana is named after its locality of origin, "Riam Macam," in the Borneo region of Indonesia. Bucephalandra species are endemic to the island of Borneo, where they grow exclusively as rheophytes along the banks of swift-flowing rainforest streams. They anchor themselves tenaciously to basaltic rocks and riverbed gravel using highly specialized roots to withstand strong currents during flash floods. They inhabit humid, shaded environments under the canopy of the dense rainforest. Belonging to the family Araceae and the genus Bucephalandra, the exact taxonomy of these plants is complex due to high phenotypic variation.
Care, breeding and tankmates
Thrives in clean, well-oxygenated water with soft to medium hardness (KH 1-10 dKH) and a pH between 6.0 and 7.5. Regular water changes are essential to keep organic waste levels low, mimicking the pristine forest streams of its native habitat. Suitable temperature range is 20°C to 28°C. Rhizome rot is the most common issue, usually occurring if the rhizome is buried in the substrate or if water circulation is poor. Black Beard Algae (BBA) can easily colonize the leaf edges in tanks with unbalanced nutrients.

This epiphyte is perfectly suited for the foreground or midground of the aquascape. Bucephalandra motleyana "Riam Macam" should be attached directly to hardscape materials such as wood or porous rocks. Burying its rhizome in the substrate will cause it to rot and die off. Its textured, green leaves provide an excellent textural contrast when placed in crevices.
Bucephalandra motleyana "Riam Macam" is characterized by its textured, green leaves that adapt well to submerged life. The foliage often displays tiny silver speckles on the surface, adding to its visual appeal under strong lighting. It grows from a creeping rhizome that firmly attaches to surfaces using strong, specialized roots. The plant occasionally produces beautiful small white underwater flowers.
Like most Bucephalandra species, Bucephalandra motleyana "Riam Macam" exhibits a notoriously slow growth rate even under optimal conditions. The addition of CO2 injection can slightly increase the speed of development and improve leaf density. You can expect only a few new leaves per month from a healthy rhizome. Patience is key when cultivating this plant.
As a true epiphyte, Bucephalandra motleyana 'Riam Macam' should never be buried in conventional aquarium substrates like gravel or aqua soil. Its roots are functionally designed for anchoring onto hardscape materials such as porous rocks and driftwood branches. If the main rhizome is covered by substrate, it becomes highly susceptible to anoxic rot. The plant relies entirely on water column fertilization to uptake the necessary elements for healthy foliage and strong root development.
Liquid fertilization is the preferred method for feeding Bucephalandra motleyana "Riam Macam". A comprehensive fertilizer containing iron and micronutrients will enhance its textured, green appearance. Dosing should be kept lean to prevent algae from outcompeting its slow growth. Regular water column dosing ensures the leaves remain healthy and vibrant.
Root fertilization is entirely unnecessary for Bucephalandra motleyana "Riam Macam" as it does not rely on substrate nutrients. Its roots serve primarily as anchors to grip onto hardscape elements rather than for nutrient uptake. Any root tabs placed in the soil will not directly benefit the plant. Instead, focus entirely on water column enrichment.
Trimming Bucephalandra motleyana "Riam Macam" is rarely needed due to its exceptionally slow growth habit. When necessary, use sharp aquascaping scissors to cut the rhizome cleanly, ensuring each separated piece has several healthy leaves. Remove any decaying or older leaves at the base to encourage fresh growth. Regular pruning of damaged foliage helps keep the plant looking pristine.
Propagation of Bucephalandra motleyana "Riam Macam" is easily achieved by simply dividing the main rhizome. Ensure that each cut segment contains a growing tip and at least three or four established leaves for best results. Use superglue or cotton thread to attach the newly separated rhizomes to fresh hardscape. Over time, these cuttings will establish their own root systems and continue to creep along the surface.
Bucephalandra motleyana "Riam Macam" is somewhat sensitive to sudden fluctuations in water parameters, which can trigger leaf melt. It is also highly susceptible to black beard algae and green spot algae on its slow-growing leaves. Maintaining stable CO2 levels, consistent maintenance, and clean water is crucial to prevent these issues. It generally prefers slightly acidic to neutral water conditions with good flow.
Bucephalandra motleyana "Riam Macam" serves as an exquisite detailing plant in natural, forest, or jungle style aquascapes. The textured, green leaves offer a beautiful contrast against bright green mosses and light-colored rocks. It works wonderfully for highlighting small focal points or filling gaps in the hardscape structure. Its relatively compact size makes it ideal for both large setups and nano aquariums.
