- Common name
- Anubias hastifolia
- Scientific name
- Anubias hastifolia
- Category
- Aquarium plant
- Group
- Anubias
- Environment
- Large freshwater aquarium or humid paludarium
- Origin
- West tropical Africa to Angola; forest stream banks on rocks or mud
- Care level
- Intermediate
- Adult size
- A large semi-aquatic plant: petioles reach 9–67 cm and leaf blades 10–33 cm, so leaf height can approach about 1 m
- Expected lifespan
- Long-lived perennial under suitable conditions; exact lifespan is unknown
- Minimum housing
- No fixed litre minimum; use a tall aquarium or paludarium with close to 1 m potential headroom and substantial horizontal spread
- Temperature
- Unknown — no dependable species-specific numeric aquarium range was found
- pH
- Unknown — no dependable species-specific numeric aquarium range was found
- Hardness / minerals
- Unknown — no dependable numeric GH/KH range was found; maintain stable freshwater mineral conditions
- Salinity
- Freshwater; not a brackish plant
- Lighting
- Unknown species-specific requirement — start low to moderate and support emersed leaves appropriately
- Placement / zone
- Background or paludarium margin, with rhizome exposed on rock, wood or substrate surface
- Filtration
- Use gentle circulation and fine mechanical capture to keep detritus from settling on slow leaves and around the rhizome. Do not aim a harsh jet at new growth, and guard intakes after division or attachment work.
- Aeration
- Maintain ordinary whole-aquarium gas exchange. In low-flow hardscape pockets, ensure water still exchanges around the rhizome; in carbon-injected systems protect night-time oxygen.
- Maintenance
- Keep the rhizome exposed, remove failing leaves at the petiole base, clean persistent algae and sediment gently, inspect attachments, and divide only established branching growth with clean tools.
Identity and search names
Species profile for Anubias hastifolia, not every arrowhead-shaped Anubias or unrelated terrestrial aroid.
Search names: Hastate anubias, Arrowhead anubias, Amauriella hastifolia
Environment and housing
Natural habitat includes shaded forest-stream banks on rocks or mud. Provide stable humidity for emersed leaves, firm support and a fully exposed creeping rhizome.
Social structure: One clump or a spaced group of clonal divisions; no animal social structure applies. Leave room for the mature rhizome and species-specific leaf spread.
Feeding and nutrition
Feeding ecology: Balanced water-column and root-accessible nutrients without burying the rhizome
Feeding routine: Use balanced nutrients and avoid high dosing without visible deficiency.
Breeding, reproduction or spread
Divide a substantial rhizome only when each section can retain established leaves and roots.
Detailed care and app-ready planning
- Identity scope
- Species profile for Anubias hastifolia, not every arrowhead-shaped Anubias or unrelated terrestrial aroid.
- Adult size and space
- Petioles can reach 67 cm and blades 33 cm, allowing leaf height near 1 m. Provide matching headroom and horizontal clearance.
- Social structure
- One clump or a spaced group of clonal divisions; no animal social structure applies. Leave room for the mature rhizome and species-specific leaf spread.
- Swimming zone or placement
- Attached foreground, midground or emersed hardscape according to the identified species or cultivar; no animal swimming zone applies.
- Feeding ecology
- Slow-growing photosynthetic rhizome plant using light, dissolved carbon and restrained water-column nutrition.
- Feeding plan
- Use balanced nutrients and avoid high dosing without visible deficiency.
- Water stability
- Numeric temperature, pH and GH/KH limits remain Unknown. Maintain stable dechlorinated freshwater and stable humidity.
- Habitat structure
- Rhizome exposed on rock or wood, or roots placed in substrate while the rhizome remains above it, with gentle debris-clearing flow.
- Compatibility plan
- Do not place beneath a closed lid that crushes leaves or where mature foliage permanently shades small plants.
- Breeding or reproduction plan
- Divide a substantial rhizome only when each section can retain established leaves and roots.
- Quarantine
- Inspect large petioles, leaf undersides, rhizome and roots for snails, eggs, terrestrial pests, algae and rot.
- Welfare checks
- Check petiole support, leaf deformation, rhizome firmness, root health, desiccation, algae and crowding against the lid.
- Biosecurity and release
- Never release aquarium plants, fragments, substrate or wastewater into drains, ponds, dams or waterways. Check current Australian import conditions and state weed rules using the accepted botanical identity and all known synonyms.
- Main risk
- Placing a very large semi-aquatic species in a small aquarium.
- Adult projected load
- Projected load is slow perennial leaf and rhizome biomass, shading, trapped detritus and viable divisions. Biological waste is low, but neglected leaves can become long-term algae and debris surfaces.
- Filtration
- Use gentle circulation and fine mechanical capture to keep detritus from settling on slow leaves and around the rhizome. Do not aim a harsh jet at new growth, and guard intakes after division or attachment work.
- Aeration
- Maintain ordinary whole-aquarium gas exchange. In low-flow hardscape pockets, ensure water still exchanges around the rhizome; in carbon-injected systems protect night-time oxygen.
- Maintenance
- Keep the rhizome exposed, remove failing leaves at the petiole base, clean persistent algae and sediment gently, inspect attachments, and divide only established branching growth with clean tools.
- Overridable warnings
- Non-overridable: never bury the rhizome or release viable divisions, leaves with growing tissue, substrate or aquarium water. Light, fertiliser and attachment methods may vary only while the rhizome remains firm, exposed and free of persistent algae or rot.
- Identity
- Accepted species Anubias hastifolia. Amauriella hastifolia is a historical synonym. Hastate leaves alone are not sufficient identification without provenance.
- Environment
- Natural habitat includes shaded forest-stream banks on rocks or mud. Provide stable humidity for emersed leaves, firm support and a fully exposed creeping rhizome.
- Feeding
- Supply balanced nutrients through water and roots. Large leaves do not mean high fertiliser demand, and excess light may create persistent algae.
- Breeding
- Propagate by dividing a mature healthy rhizome. Flowering and seed production are not required for aquarium propagation.
- Adult size and space
- Petioles can reach 67 cm and blades 33 cm, allowing leaf height near 1 m. Provide matching headroom and horizontal clearance.
- Growth Rate
- Slow to moderate depending on emersed conditions; aquarium growth is usually slow.
- Lighting Plan
- Begin low to moderate. Emersed leaves need light without overheating or desiccation.
- Carbon Plan
- Injected carbon dioxide is optional for submerged growth; stable humidity is more important for emersed foliage.
- Nutrient Plan
- Use balanced nutrients and avoid high dosing without visible deficiency.
- Substrate Plan
- Keep the rhizome on the surface or attached to hardscape; roots may enter mud or substrate.
- Propagation plan
- Divide a substantial rhizome only when each section can retain established leaves and roots.
- Biosecurity and release
- Never release aquarium plants, fragments, substrate or wastewater into drains, ponds, dams or waterways. Check current Australian import conditions and state weed rules using the accepted botanical identity and all known synonyms.
Compatibility, welfare and risk
Compatibility: Only suitable where metre-scale leaf height and broad petioles will not shade or crush smaller plants.
Welfare: Check petiole support, leaf deformation, rhizome firmness, root health, desiccation, algae and crowding against the lid.
Main warning: This is a metre-scale semi-aquatic Anubias, not a nano aquarium plant. A small tank and buried rhizome are both serious placement errors.
Biosecurity and release
Never release aquarium plants, fragments, substrate or wastewater into drains, ponds, dams or waterways. Check current Australian import conditions and state weed rules using the accepted botanical identity and all known synonyms.
