About Dwarf Anubias

Anubias nana · also called Dwarf Anubias, Anubias Nana · houseplant

Dwarf Anubias is the most popular aquarium plant globally, prized for its compact size, deep-green rounded leaves, and extreme adaptability to low light and a wide range of water parameters. A West African native, it grows on rocks and wood in shaded streams. Virtually indestructible in freshwater aquariums, paludariums, and terrariums.

Mature size: Leaves 3–7 cm long; plant typically 5–15 cm tall and 10–20 cm wide; slower-growing and more compact than Anubias barteri

Watch for — Green spot algae on leaves: Hard green spots on the slow-growing leaves are caused by excess light or phosphate imbalance. Reduce lighting duration, add nerite snails (effective grazers of this algae type), and ensure phosphate levels are balanced relative to nitrate.

Indoor size vs how big it gets in the wild

Dwarf Anubias does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect leaves 3–7 cm long. In the ground with no restriction it is a completely different plant — plant typically 5–15 cm tall and 10–20 cm wide; slower-growing and more compact than anubias barteri — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

Dwarf Anubias is a slow grower. Realistically, expect many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Its feeding profile backs this up: very light feeder. a dilute all-in-one liquid aquarium fertiliser at half dose weekly is sufficient. co2 injection is not required. in heavily planted aquariums, existing nutrient levels from fish bioload are often adequate without additional supplementation.

Want this turned into the right next pot at the right moment? The pot size calculator and the dwarf anubias repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast dwarf anubias grows.

How to keep dwarf anubias smaller

You are not stuck with the maximum size. For dwarf anubias specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — dwarf anubias takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
A trim once or twice a season is usually enough to hold its length.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of dwarf anubias should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow dwarf anubias bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for dwarf anubias the accelerators are:

More (indirect) light dramatically lengthens the vines and enlarges the leaves.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

Light is almost always the ceiling. The dwarf anubias light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When dwarf anubias outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for dwarf anubias:

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the dwarf anubias repotting guide. If you want more of this plant instead of a bigger one, the dwarf anubias propagation guide turns prunings into new plants.

Dwarf Anubias size — frequently asked questions

How big does dwarf anubias get?

Dwarf Anubias reaches leaves 3–7 cm long when grown indoors, and far larger where it grows unrestricted (plant typically 5–15 cm tall and 10–20 cm wide; slower-growing and more compact than anubias barteri). Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Is dwarf anubias slow or fast growing?

Dwarf Anubias is a slow grower. Expect many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Dwarf Anubias does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims.

How long does dwarf anubias take to reach full size?

Roughly many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Light, pot size and feeding move that timeline more than anything else.
