📍 West Africa

Anubias Gigantea is the largest species in the anubias genus, with broad, leathery leaves that can exceed 20 cm (7.9 in) in length and reach 60–80 cm (23.6–31.5 in) in total height in mature specimens. It makes a dramatic focal-point background plant in large aquariums and is equally at home emersed in paludariums. Despite its impressive size it shares the same forgiving, low-maintenance care profile as all anubias.

Tank Mates

Otocinclus

Peaceful algae grazers that won't damage hardy Anubias leaves

excellent

Gentle bottom-dweller that respects plants and prefers similar warm water

excellent

Red Cherry Shrimp

Excellent algae control without harming plant tissue; thrive in same parameters

excellent

Anubias Barteri

Companion plant with identical care requirements; creates layered background

excellent

Java Fern

Rhizome plant with matching low-light tolerance and slow growth rate

excellent

Bristlenose Pleco

Nocturnal algae eater that respects established plants; may uproot softer neighbors but leaves Anubias untouched

Common Diseases

Rhizome Rot

Symptoms

Soft, blackened rhizome tissue; mushy appearance; foul odor; leaf yellowing and detachment

Treatment

Remove plant and trim away all rotted tissue with sterile blade. Replant in fresh substrate with improved water circulation and reduced organic buildup. Ensure rhizome is not buried.

Algae Overgrowth (Black Beard Algae)

Symptoms

Black or dark red filamentous algae coating leaves and rhizome; reduced light penetration

Treatment

Manually remove affected leaves; increase water changes; reduce light duration to 8-10 hours daily; add algae-eating fish like Otocinclus or shrimp; consider hydrogen peroxide spot treatment (1-2 mL per 10 gallons) as last resort.

Nutrient Deficiency

Symptoms

Pale or yellowing new leaves; stunted growth; thin, weak leaf structure

Treatment

Dose liquid all-in-one fertilizer 1-2 times weekly; ensure adequate fish bioload; perform regular water changes to maintain nutrient balance; consider macronutrient supplementation if using high-light setups.

Melting (Emersed to Submersed Transition)

Symptoms

Rapid leaf deterioration and shedding after submersion; transparent or dissolving leaf tissue

Treatment

This is temporary adaptation; maintain stable water parameters and patience. Trim damaged leaves to redirect energy to new growth. Ensure low-to-medium lighting and good water circulation during adjustment period (2-4 weeks).
