What is Anubias?

Anubias is a genus of aquatic plants that belongs to the family Araceae. These plants are native to the tropical parts of Africa, and you can usually find them in freshwater places like rivers and streams. Aquarists love Anubias plants, and aquascaping uses them a lot.
Anubias plants are known for being hardy and easy to care for, so both new and experienced aquarium owners can keep them. Most of the time, they have wide, dark green leaves that grow on thick stems or rhizomes. Depending on the type and species, the leaves can be different sizes and shapes.
One thing that makes Anubias plants stand out is that they can grow well in low light, which makes them perfect for aquariums that do not get a lot of light. They are also slow-growing plants, which means that they do not need as much pruning and care as other aquatic plants.
Aquariums often have Anubia plants in them to make them look more natural and pretty. You can use fishing line or glue that is safe for plants to attach them to driftwood, rocks, or other hardscape materials. This makes an arrangement that looks nice and gives fish and other aquatic animals places to hide.
Anubias plants do best in water that is between 72°F and 82°F (22°C and 28°C) and has a pH between 6.0 and 7.5. They can live in a wide range of hardness levels in the water. Most of these plants’ nutrients come from the water and fish waste, so fertilizing them regularly is not usually necessary. But adding extra liquid or substrate fertilizers can help plants grow better.
Anubias plants are semi-aquatic, which means you should not bury their rhizomes in the substrate. If you bury the rhizome, it can start to rot. Instead, the rhizome should be left out in the open, while the roots can be buried gently or stuck to a surface.
Overall, Anubias plants are popular choices for aquarium owners because they are hardy, can grow in low light, and look nice.
What Does Anubias Look Like?
Anubias plants look different from other plants, so they are easy to spot. Here are some common things about Anubias plants:
- Leaves: The broad, dark green leaves of an anubias plant are often heart-shaped or lanceolate. Depending on the species and type of Anubias, the leaves can be different sizes. The leaves of some species are bigger than those of others. Most leaves have a smooth, shiny surface.
- Stems and Rhizomes: The leaves of anubias plants grow from thick stems or rhizomes. The rhizome is a horizontal stem that creeps along the ground. It stores food and makes new plants grow. Anubias plants usually have brown or reddish-brown rhizomes.
- Roots: The rhizome of an anubias plant sends out a network of roots that hold the plant to the substrate or other surfaces. The roots are often thin and light in color, which gives the plant a strong hold.
- Growth Habit: Anubias plants tend to grow slowly, so they do not need to be trimmed or pruned as often as other plants. They tend to grow in a clump or rosette shape, with the leaves coming out at regular intervals from the rhizome.
- Flowering: When the conditions are right, Anubias plants can make small flowers that are white or cream-colored. But flowering is not very common in aquariums. It is more common in emersed conditions.
- Size: Anubias plants can be different sizes depending on the species and how they grow. Some species, like Anubias barteri, can grow to be 12 inches (30 cm) or taller, while others, like Anubias nana, tend to stay smaller and only grow to be 10–15 cm (3–4 inches) tall.
It is important to know that the genus Anubias has many species and varieties, each with its own leaf shape, size, and way of growing. Anubias barteri, Anubias nana, Anubias coffeefolia, and Anubias congensis are all popular species of Anubias. Different species may look a little different, but they all have the same general traits.
Do Bettas Like Anubias?

Yes, bettas (Siamese fighting fish) generally like Anubias plants. Anubias is a popular choice for betta fish tanks and is often recommended as a suitable plant for betta habitats. Here are a few reasons why Anubias is beneficial for bettas:
- Leaf Structure: Anubias plants have broad leaves that provide bettas with ample resting places near the water’s surface. Betta fish have a labyrinth organ, which allows them to breathe atmospheric air. The large leaves of Anubias create resting spots where bettas can rest and access the air above the water surface.
- Hiding Places: The dense foliage of Anubias plants provides hiding places for bettas. Bettas are solitary fish and often appreciate having areas where they can retreat and feel secure. Anubias plants with their thick leaves and sturdy stems offer bettas a sense of shelter, reducing stress and promoting their well-being.
- Compatibility with Betta Behavior: Bettas are known for their finicky nature and can be sensitive to changes in their environment. Anubias plants are hardy and can withstand the curious and sometimes destructive behavior of bettas. The leaves are generally tough and not easily torn, making them suitable for betta tanks.
- Low-Light Tolerance: Anubias plants can thrive in low-light conditions, which is beneficial for betta tanks. Bettas prefer dimly lit environments, and Anubias can survive and grow well with limited artificial lighting. This makes it easier to maintain a betta tank with Anubias plants without the need for intense lighting setups.
- Easy Care: Anubias plants are low-maintenance and require minimal care. They do not have demanding lighting or nutrient requirements, making them suitable for beginner betta keepers or those who prefer low-maintenance aquariums. Anubias plants can adapt to a wide range of water parameters, which is beneficial for betta habitats.
When adding Anubias to a betta tank, it’s important to properly secure the plant in the substrate or attach it to hardscape materials such as rocks or driftwood. The rhizome should be kept above the substrate to prevent rotting. Bettas may also appreciate if the leaves are positioned near the water’s surface, allowing them easy access to the air.
Overall, Anubias plants can enhance the aesthetics of a betta tank while providing functional benefits for the betta fish.
