Anubias barteri 'Gigantea' is the largest and most commanding of the Anubias barteri varieties, producing broad, deep green leaves that can reach 15–20 cm in length on thick, creeping rhizomes. It brings structural weight and permanence to aquascapes in a way that few other plants can — a single well-placed specimen becomes the anchor of an entire layout. Like all Anubias, it grows slowly, tolerates low light, and requires no CO₂, making it one of the most genuinely low-maintenance plants available for shrimp tanks, hardscape-forward setups, and blackwater biotopes alike.

What to Expect

Growth & Behavior Over Time

Large, bold leaf structure — individual leaves are significantly broader and longer than standard Anubias barteri, creating a dominant visual presence that works as a focal point or backdrop in mid to large aquariums. Slow but steady rhizome growth — 'Gigantea' grows slowly even by Anubias standards, adding a few leaves per month under good conditions. Patience is rewarded with a plant that, once established, is virtually indestructible. Attaches naturally to hardscape — the rhizome grips driftwood and rocks over time, eventually anchoring itself firmly without any assistance. Initial attachment with thread or glue speeds up the process. Tolerates low light exceptionally well — one of the most light-tolerant aquatic plants available; grows well in shaded areas of the tank where most other plants would struggle or decline. Algae on leaves is manageable — the slow growth rate and large leaf surface can attract algae under high light. Keeping light intensity moderate and ensuring good water flow across leaves prevents most algae buildup. Shrimp actively use the broad leaves — the large leaf surface accumulates biofilm that Neocaridina, Caridina, and snails graze on consistently, making 'Gigantea' a genuinely functional addition to any shrimp tank.

How to Set It Up

Getting Started

1 Never bury the rhizome — the thick horizontal stem that connects the roots and leaves must remain above the substrate. Burying it causes rot and will kill the plant. Attach it to hardscape or rest it on the substrate surface instead.

2 Attach to driftwood or rock — use thin thread or super glue gel to fix the rhizome to a piece of driftwood or stone. Within a few weeks the roots will grip the surface naturally and the thread can be removed or left to dissolve.

3 Place in low to medium light — 'Gigantea' does not need strong lighting and actually performs better away from intense light, which can encourage algae growth on its broad leaves. Shaded midground or background positions suit it well.

4 Allow time to establish — Anubias often goes through a slow adjustment period after being introduced to a new tank. Some leaf yellowing during the first few weeks is normal; new growth will emerge once the rhizome has settled.

💡 Bonus Tip

If algae begins to form on the leaves, a brief spot treatment with liquid carbon or a short blackout period will clear it without harming the plant — Anubias is one of the few species tough enough to handle a 3-day blackout and come out looking fine.
