Anubias barteri nana 'Mini Coin'

Anubias barteri var. nana 'Mini Coin'
Common Name: Mini Coin Anubias

Anubias barteri var. nana 'Mini Coin' is one of the tiniest known cultivars of Anubias, featuring perfect, coin-shaped leaves barely larger than 0.5 cm in diameter. This slow-growing rhizome plant forms dense, low clusters of rich green foliage and is ideal for nano aquascapes, micro terrariums, and intricate hardscape designs. Originally selected and propagated in specialised nurseries, ‘Mini Coin’ is prized for its miniature size, ornamental shape, and extreme durability.

Just like other Anubias types, it must be mounted on hardscape materials like driftwood, rocks, or cork bark. It thrives in humid, low-light environments and does not require nutrient-rich soil or CO₂ supplementation. In aquariums, it's frequently used for foreground layering and small-scale aquascaping. In terrariums or vivariums, its scale and structure make it ideal for tiny landscapes or bonsai-style hardscape accents.

1. Special Features:

   • Ultra-compact with tiny, round, coin-like leaves

   • Excellent for nano or bonsai layouts

   • Tolerant of variable conditions and resistant to rot

2. Companion Compatibility:

   • Great with mosses, Bucephalandra, and micro orchids

   • Fully safe with amphibians, reptiles, fish and insects

3. Lifecycle:

   • Perennial

4. Dormancy Needs:

   • None

5. CO2 Demand:

   • Low (can benefit slightly from CO₂ in aquariums)

6. Animal Compatibility:

   • Perfectly safe for bioactive enclosures and aquariums

• Do not bury the rhizome; mount it on driftwood, rocks, or cork using glue or thread.

• Suitable for the lowest zones of terrariums or nano tank scapes.

• Ensure good airflow to prevent excess condensation or rot on the leaves.

• Watering (Terrarium): Keep moist via ambient humidity or light misting.

• Light: Low to medium; indirect light is ideal to prevent algae buildup.

• Humidity: Needs 60–90% to thrive when emersed.

• Feeding: Minimal; occasional aquarium fertiliser is enough.

• Pruning: Very slow-growing; remove any damaged leaves by hand.
