Anubias Congensis
Anubias afzelii
Plantae›Tracheophyta›Magnoliopsida›Araceae
📍 West Africa
Anubias Congensis (often sold as Anubias lanceolata) produces elongated, lance-shaped leaves on tall petioles, reaching 30–40 cm (11.8–15.8 in) in height and making it one of the larger anubias suitable for midground to background use. Its upright, narrow leaf profile creates vertical interest against broader-leafed plants. Like all anubias, the rhizome must remain exposed and anchored to wood or rock.
Tank Mates
Peaceful algae grazers that won't damage plant leaves; ideal for planted tanks
Gentle invertebrates that graze algae and won't uproot or damage hardy plants
Small, peaceful fish that occupy mid-water column without disturbing plants
Excellent companion plant with similar care requirements and growth rate
Closely related anubias species with identical care needs; creates cohesive planted design
Peaceful, non-destructive fish that appreciate planted environments and low light
Common Diseases
Anubias Rot (Rhizome Decay)
Blackening or mushy rhizome, foul odor, leaf yellowing and melting
Ensure rhizome remains exposed to water flow; improve water circulation; remove affected portions with sterile tools; reduce organic buildup with water changes
Algae Overgrowth (Black Beard Algae)
Black or dark red fuzzy growth on leaves and rhizome, especially in low-flow areas
Increase water flow around plant; reduce light duration to 8-10 hours daily; manually remove affected leaves; add algae-eating fish like Otocinclus or shrimp
Nutrient Deficiency
Yellowing leaves, stunted growth, pale new growth, holes in older leaves
Dose all-in-one liquid fertilizer weekly; ensure adequate macro and micronutrients; check water parameters; perform regular water changes to prevent nutrient lockout
Melting (Emersed to Submersed Transition)
Rapid leaf deterioration and shedding after planting in aquarium
This is normal adaptation; maintain stable water parameters and patience; old leaves will shed and new submersed leaves will grow; avoid over-fertilizing during transition
