Bucephalandra Black Tears

This Bucephalandra has slender, elongated leaves that are often described as teardrop-shaped. The foliage is usually a deep green and may appear darker along the edges or under certain lighting. Actual colour and leaf proportions can vary between specimens.

It grows slowly from a thin, creeping rhizome and forms a low cluster attached to rock or wood. Its narrow leaves make it useful as a foreground or midground accent where a round-leaved Bucephalandra would look too heavy.

In the first few weeks, a beginner may see little outward growth. The best early signs are a firm rhizome, intact roots, and the start of a new leaf.

Essentials

• Low to medium light is the safest starting point.
• Attach the plant to rock or wood. Keep the rhizome above the substrate.
• Keep temperature and water chemistry reasonably stable rather than chasing one exact value.
• Provide gentle to moderate circulation so debris does not sit on the slow-growing leaves.
• Use a sensible complete aquarium fertiliser routine if the tank does not already receive enough plant nutrients.

Optional improvements

• Stable injected CO₂ can improve growth speed and density.
• A mature aquarium is not an absolute requirement, but an established, stable tank is usually easier because sudden swings and early algae are less common.
• Shaded or partly shaded placement can reduce algae pressure on the slow-growing leaves.

Beginner setup

• Established filtered aquarium
• Low or moderate light period
• Small rock or wood attachment point
• Gentle water movement around the leaves
• Regular but restrained fertilising
• No buried rhizome

Water and maintenance

A practical starting range is about 20–28 °C and mildly acidic to mildly alkaline freshwater. These are broad aquarium guidelines for unidentified trade-form Bucephalandra, not proven limits for this named form. Avoid sudden changes and watch the actual plant for stress.

No nutrient-rich substrate is required because the plant is normally attached to hardscape. Its exposed roots and leaves can use nutrients from the water column. Dose a complete aquarium fertiliser carefully when the tank’s livestock load and feeding do not provide enough nutrients.

CO₂ level

Injected CO₂ is optional. This plant can be grown in a low-tech aquarium without injection when light, fertilising, flow, and water conditions remain stable.

Stable CO₂ may improve the speed and strength of new growth and can help the plant form a denser colony. It may also make colour or surface sheen more noticeable, but it cannot guarantee a particular colour, leaf size, or growth rate.

CO₂ adds another setting that must remain consistent. Sudden changes can make an already slow-growing plant harder to manage. Use moderate light, steady CO₂, and an appropriate fertiliser routine together. Do not raise the light simply because CO₂ is present.

Before placing the plant

• Inspect the leaves, roots, and rhizome. Remove loose, fully decayed material with clean scissors.
• If it arrives in a pot, slide it out carefully and remove as much rock wool as possible without tearing healthy roots.
• Rinse the plant in clean aquarium-safe water and check for hitchhiking snails, algae, or damaged tissue.
• Do not split a very small plant merely to create more portions. Divide only where there are clear rhizome sections with their own leaves and roots.

Positioning

• Place the plant on rock or wood with the rhizome visible above the surface.
• Roots may touch or enter gravel, but the horizontal rhizome must not be buried.
• Leave enough open space around the leaves for water movement and future slow expansion.

If sold as tissue culture

• Remove the plant from the cup and rinse away all nutrient gel.
• Separate it gently into small natural clumps instead of tearing every shoot apart.
• Attach each clump to hardscape with the rhizome exposed.

Suitable attachment methods

• Thread: tie the rhizome loosely with cotton thread. Remove or allow the thread to break down after the roots have gripped the surface.
• Fishing line: use a loose wrap where a transparent tie is preferred. Check that it does not cut into the rhizome as the plant grows.
• Cyanoacrylate super glue gel: dry a small point on the rock or wood, add a tiny drop, and press a root or the underside of the rhizome in place for several seconds. Avoid covering the whole rhizome with glue.
• Mesh: use only for very small portions, and hold them gently against stone or wood. Do not crush the rhizome under tight mesh.

Choose a shaded or moderately lit surface with some water movement. Never bury the rhizome, even when the roots are placed close to substrate.

Routine trimming

Because this plant grows slowly, frequent trimming is usually unnecessary. Use clean, sharp aquascaping scissors.

• Remove a damaged, melting, or heavily algae-covered leaf by cutting its leaf stalk close to the rhizome without cutting into the rhizome.
• Do not remove a large share of healthy leaves at once. The plant needs its remaining leaves while it establishes.
• To reduce an overgrown clump, cut between healthy rhizome sections rather than cutting through the middle of a leaf cluster.
• Leaf-only trimmings cannot normally be replanted. A reusable trimming must include a healthy piece of rhizome, leaves, and preferably roots.

Selective leaf removal keeps the clump tidy. Rhizome division controls its spread and can create separate plants, but density develops slowly after cutting.

Rhizome division

The practical propagation method is to divide the rhizome.

• Wait until the plant has more than one healthy growing section.
• Choose a section with several healthy leaves and, where possible, its own roots.
• Use clean, sharp scissors or a blade to make one clean cut through the rhizome.
• Attach the new section to rock or wood with the rhizome exposed.
• Keep conditions stable while both sections recover.

A new section is ready to separate when it has enough leaves and roots to remain stable on its own. Avoid dividing a newly purchased or melting plant.

Normal adjustment

Slow establishment is normal. A newly added plant may spend several weeks producing roots or replacing older leaves before obvious outward growth appears.

Plants grown above water before sale may shed some older leaves while producing leaves better suited to permanent submersion. Limited loss of older leaves can be part of adjustment when the rhizome stays firm and new growth eventually appears.

What to monitor

• Normal: firm rhizome, stable roots, occasional older-leaf loss, and slow new growth.
• Needs attention: a soft or darkening rhizome, repeated loss of every new leaf, worsening decay, or debris and algae coating the leaves.
• Check recent changes in light, CO₂, fertiliser, temperature, flow, and water chemistry before making another adjustment.

Leaf colour, size, and density can change under different light and nutrition levels. Compare new growth over several weeks rather than judging the plant from one older leaf.
