How to Care for Anubias Plants in Your Aquarium

Introduction

Anubias is one of the most popular aquarium plants for beginners and experienced aquascapers alike — and for good reason. These hardy, slow-growing plants thrive in a wide range of water conditions, require minimal light, and add a lush, natural look to any tank. Whether you're setting up your first planted aquarium or looking to add some greenery to an established setup, Anubias is an excellent choice.

Why Choose Anubias?

Anubias plants are native to the rivers and streams of West Africa, where they grow attached to rocks and driftwood in shaded, slow-moving water. This background makes them uniquely suited to aquarium life:

  • Low light tolerance: They thrive under standard aquarium lighting and don't require expensive grow lights.
  • Slow growth: Less pruning, less maintenance.
  • Broad leaves: Provide excellent hiding spots for fish and shrimp.
  • Versatile placement: Can be attached to driftwood, rocks, or left free-floating.

Water Parameters

Anubias are very forgiving, but they do best in the following conditions:

  • Temperature: 22–28°C (72–82°F)
  • pH: 6.0–7.5
  • Hardness: Soft to moderately hard water
  • Lighting: Low to medium (8–10 hours per day)

How to Plant Anubias

This is the most important tip for Anubias success: never bury the rhizome in substrate. The rhizome is the thick horizontal stem from which the roots and leaves grow. Burying it will cause it to rot and kill the plant.

Instead, attach your Anubias to driftwood or rocks using fishing line or aquarium-safe glue. Over a few weeks, the roots will naturally grip the surface and the line can be removed. You can also wedge the plant between rocks or let it float freely — it will still grow.

Fertilisation & CO2

Anubias are light feeders. A basic liquid fertiliser added weekly is usually sufficient. They do not require CO2 injection, making them ideal for low-tech setups. In fact, too many nutrients can encourage algae growth on their slow-growing leaves — a common issue called algae on Anubias.

Common Problems & Solutions

  • Algae on leaves: Reduce lighting duration or intensity. Add algae-eating shrimp or snails to your tank.
  • Yellow leaves: Usually a sign of nutrient deficiency. Add a balanced liquid fertiliser.
  • Rotting rhizome: The rhizome has been buried. Remove the plant, trim the rotted section, and reattach it to a hard surface.
  • Slow growth: This is normal! Anubias grow slowly by nature. Be patient.

Compatible Tank Mates

Anubias pair beautifully with peaceful community fish. Their broad leaves make great resting spots for bettas and hiding places for shrimp. They work especially well in tanks with guppies, tetras, and dwarf shrimp.
