Anubias Nangi Rare Plant Care Guide: Compact Hybrid
Hybrid Anubias rarely earn collector status, but Nangi is the exception that aquascapers track down for its compact form and unusually rounded leaves. This Anubias Nangi rare plant care guide draws on three years of grow-out and propagation at Gensou Aquascaping at 5 Everton Park. The plant rewards patience with one of the most refined epiphyte silhouettes available to the hobby.
Origin of the Hybrid
Nangi is a horticultural cross between Anubias barteri var. nana and Anubias gilletii developed in West African nurseries in the early 2000s. The hybrid combines the small stature of nana with the slightly elongated leaf of gilletii, producing a plant that sits between the two parents in size and form. Singapore stock typically traces back to European tissue culture sources.
Visual Identification
Leaves are 3-4 cm long, oval-elliptic with a noticeably softer green than nana petite. The rhizome is thinner than barteri but thicker than nana petite, sitting between 4 and 6 mm in diameter. New leaves emerge tinged copper before settling to deep green. The leaf surface carries a subtle gloss under direct lighting.
Why Collectors Prize It
Nangi maintains its compact form even under high light, where nana petite can elongate awkwardly. The plant flowers regularly underwater once established, producing the distinctive white spathe of the genus. Compact growth combined with reliable underwater flowering makes it a showpiece for nano displays.
Tank Size and Placement
Nangi suits tanks from 20 litres upward. Place it as a mid-ground or foreground accent on small stones or the side of branchy wood. Avoid the back of the tank because the foliage is too small to register at distance. Multiple rhizomes spaced 5-7 cm apart create a uniform low band that reads beautifully in iwagumi or biotope styles.
Lighting Tolerance
Anubias Nangi accepts 25-80 PAR at the rhizome without algae problems provided water flow keeps detritus off the leaves. The hybrid actually tolerates higher light better than other anubias because the compact leaf packing reduces algae shadowing. A 6500K spectrum suits the leaf colour without washing it out.
Water Parameters
The plant accepts a remarkably wide chemistry range. GH 2-15, KH 1-10 and pH 6.0-8.0 all work. Singapore PUB tap water suits the plant unmodified. Temperature should stay between 22-28°C; sustained periods above 30°C trigger leaf damage and increase susceptibility to rhizome rot. See our broader anubias aquarium plant guide for genus-wide notes.
Attachment Method
Glue the rhizome to stone or wood with a small dab of cyanoacrylate gel. Never bury the rhizome; rot is fatal and irreversible. The fine roots will anchor the plant within four to six weeks, after which the glue can be trimmed away if desired. Read how to attach plants to wood rock for technique notes.
Fertilisation Strategy
As an epiphyte the plant feeds primarily through water-column dosing. A standard all-in-one liquid fertiliser at half manufacturer dose three times weekly suits Nangi well. Iron supplementation brings out richer leaf colour. Root tabs are unnecessary since the rhizome is not in substrate.
CO2 Response
Pressurised CO2 doubles growth rate but is not required. Without CO2 expect one new leaf every six to eight weeks; with CO2 expect one every three weeks under stable conditions. The leaf form remains compact regardless of CO2 status, unlike many stem plants that change morphology dramatically.
Propagation and Common Problems
Divide the rhizome with a clean blade once it carries at least six leaves and a visible secondary growth point. Each division should retain three or more leaves and a healthy root segment. New growth resumes within four weeks. Our anubias rhizome division propagation piece walks through the cut sequence. Black spots on older leaves usually signal calcium or potassium deficiency rather than disease; review your dosing. Rhizome rot smells distinctly acidic and means the plant is buried or sitting in low-flow detritus. Slow growth in a healthy-looking specimen often means light is too low rather than too high. The how to fix black spots on anubias leaves diagnostic covers the common causes.
Sourcing, Pricing and Final Notes
Genuine Nangi rhizomes appear at Green Chapter, Nature Aquarium and occasional Carousell offerings from collector keepers. Expect $18-35 SGD for a well-established rhizome with five to seven leaves. Tissue culture cups are cheaper at $14-20 but require a longer establishment period before they look display-ready. Anubias Nangi is one of the most refined small-format epiphytes available and rewards careful placement more than aggressive growth coaxing. Treat it like a sculpture rather than a plant; pick the rock or wood carefully, place a single rhizome in the right spot, and let the plant grow into the position over twelve months.
