Introduction & History
Anubias barteri var. nana 'Petite' (Petite Anubias) is a slow-growing rhizomatous aquatic plant in the family Araceae, suitable for aquarium cultivation. It produces white flowers in none. An excellent choice for planted aquariums, it reaches 5 cm tall with dark green foliage.
Pond zone: submerged • USDA zones: 10-12 • Growth: slow
Chromosome count: 2n=24–60+ (highly variable) • Pollination: fly and beetle-pollinated; spathe-and-spadix inflorescence traps pollinators temporarily • Key secondary metabolites: calcium oxalate raphides (irritant crystals), aromatic compounds
Extremely diverse family including both aquatic genera (Cryptocoryne, Pistia) and terrestrial aroids; calcium oxalate crystals cause oral irritation if ingested raw
Botanical Description
Anubias barteri var. nana 'Petite' is a member of the Araceae family, selected for compact growth habit and ornamental value in enclosed aquatic systems. Leaves vary from finely dissected to broad, and coloration ranges from green through red to bronze depending on species and light intensity. Mature plants reach 5 cm in height with a 5 cm spread under optimal aquatic growing conditions.

Group Water Chemistry Guide
Aquarium plants are selected for growth in enclosed, artificially lit systems. Successful planted aquariums require a balance of light (30–50 µmol/m²/s PAR for moderate-light plants, 50–100+ for high-light species), CO₂ (20–30 ppm), and nutrients (macro: N, P, K; micro: Fe, Mn, Zn, Cu). The Estimative Index (EI) dosing method provides non-limiting nutrients with weekly water changes. Water temperature for tropical setups is 22–28°C, pH 6.0–7.5. Aqua soil substrates buffer pH downward and provide root nutrition for 12–18 months.
Planting & Establishment
Proper establishment is critical for Anubias barteri var. nana 'Petite'. Follow the planting guide below for your specific aquatic environment (pond, container, or aquarium).
Planting Guide — Aquarium Plant
Aquarium plants require proper substrate (2–4 cm aqua soil or enriched gravel), adequate lighting, and usually CO₂ supplementation for optimal growth. Plant stems by pushing 2–3 cm into substrate using aquascaping tweezers. Foreground carpet plants should be divided into small portions and planted in a grid pattern, 2–3 cm apart. Epiphytes (Anubias, Java fern, Bucephalandra) are attached to hardscape, not planted in substrate. Use the Dutch or Nature Aquarium styles as design templates. Start with fast-growing species (Hygrophila, Rotala) to outcompete algae during the initial cycling period (4–8 weeks).
Climate & Hardiness
Anubias barteri var. nana 'Petite' is rated as varies by cultivar and suitable for USDA hardiness zones 10-12. Water temperature management is the primary climate consideration for aquatic plants, as water buffers temperature changes more slowly than air.
Zones 10–12
Overwintering Guide
Aquarium plants in heated indoor tanks are unaffected by outdoor winter conditions. However, reduced natural daylight in winter can affect room temperature and ambient light. Ensure heaters maintain stable temperature (22–28°C for tropical setups). Adjust photoperiod timing (use timers) to maintain consistent day length year-round. Reduce fertiliser dosing slightly if plant growth slows in winter, as reduced ambient warmth can slow metabolism even in heated tanks.
🌍 Distribution Map
Native range: Cameroon
Propagation
Aquarium plants are propagated by stem cuttings (trim and replant tops), division (separate clumps at the root), adventitious plantlets (detach daughter plants from runners or leaves), and tissue culture (TC) for mass production. Most stem plants root readily from cuttings within 5–10 days.
Diseases & Problems
Common Problems
Algae overgrowth: Green or brown algae coating leaves. Caused by excess light or nutrients. Reduce photoperiod, improve CO2, and manually remove affected leaves. Melting / transplant shock: Leaves deteriorate after moving. Maintain stable water parameters; the plant usually recovers within 2-3 weeks. Iron deficiency (chlorosis): New leaves emerge pale or yellowish. Add chelated iron fertilizer or use root tabs containing micronutrients. Potassium deficiency: Pinholes appear in older leaves. Supplement with a potassium-based aquarium fertilizer. Snail damage: Pest snails (bladder, pond) can chew holes in soft leaves. Control populations manually or with snail-eating fish like Assassin Snails.1. Water quality first — most problems stem from poor water chemistry, overcrowding, or nutrient imbalance
2. Quarantine new plants — isolate new additions for 2 weeks to prevent introducing pests and diseases
3. Remove affected material — promptly cut and dispose of diseased leaves to prevent spread
4. No pesticides in water — conventional pesticides are toxic to aquatic life; use biological and cultural controls only
5. Balanced ecosystem — a diverse community of plants, fish, and invertebrates provides natural pest control
Pond Design & Placement
Anubias barteri var. nana 'Petite' contributes both aesthetic beauty and ecological function to water garden design. Position according to its specific depth requirements and growth habit for optimal performance.
Design Tips — Aquarium Plant
Design aquarium layouts using the principles of depth and perspective: tall stem plants (Rotala, Ludwigia) in the background, mid-height species (Cryptocoryne, Echinodorus) in the midground, and carpet plants (Eleocharis, Hemianthus) in the foreground. Create focal points using specimen plants or hardscape (stones, driftwood) following the golden ratio. The Iwagumi, Dutch, and Nature Aquarium styles each offer distinct aesthetic frameworks. Ensure sufficient spacing for mature growth — aquascapers often overplant initially and thin as the layout develops.
Aquarium Guide
Anubias barteri var. nana 'Petite' is suitable for aquarium cultivation. Success requires balancing the key growth factors: light intensity and duration, CO₂ concentration, macro and micro nutrient availability, and water temperature. Begin with a moderate approach — high-tech setups (high light + CO₂ injection) require precise management, while low-tech setups (low-moderate light, no CO₂) are more forgiving.
Wildlife & Ecology
Anubias barteri var. nana 'Petite' provides valuable ecological services in aquatic ecosystems, including habitat provision, water quality improvement, and food web support.
Water Quality & Filtration
Aquatic plants, including Anubias barteri var. nana 'Petite', play a vital role in maintaining water quality through biological filtration. They absorb dissolved nutrients (nitrogen and phosphorus compounds) that would otherwise fuel algae growth, produce oxygen during photosynthesis, and provide surfaces for beneficial bacterial biofilms that process organic waste. A well-planted pond or aquarium significantly reduces the need for mechanical filtration and chemical treatments.
• Nitrogen removal: Plants absorb ammonium (NH₄⁺) and nitrate (NO₃⁻) for growth; emergent plants additionally support denitrifying bacteria in their root zones
• Phosphorus absorption: Dissolved phosphate is taken up directly by plant roots and leaves; this is the most effective natural method of phosphorus removal
• Oxygenation: Submerged plants release oxygen during photosynthesis, raising dissolved O₂ levels critical for fish and beneficial bacteria
• Sediment stabilisation: Root systems bind substrate particles, reducing turbidity and resuspension of bottom sediment
• Allelopathy: Some aquatic plants release biochemicals that inhibit algae growth (documented in Ceratophyllum, Myriophyllum, and Stratiotes)
Harvest & Conservation
Responsible stewardship of Anubias barteri var. nana 'Petite' includes managing its growth within your water feature, preventing escape into wild waterways, and sourcing plants from reputable, sustainable nurseries. Many aquatic plants are regulated or prohibited in certain jurisdictions due to their invasive potential.
Cultural & Historical Significance
Anubias barteri var. nana 'Petite' has cultural significance in water gardening traditions and aquatic horticulture. Aquatic plants have been cultivated since at least ancient Egyptian times, and the art of water gardening has evolved into a sophisticated horticultural discipline spanning formal European water features, Japanese garden traditions, and modern naturalistic pond design.
