Anubias are aquatic plants. They can grow submerged or emersed. They grow in streams, rivers and marshes in the tropical areas of Africa. These plants are a sight to behold. With their lush green color and beautifully shaped leaves, they are mostly displayed in the foreground and midground of planted aquariums. The species number is abundant enough to build a beautiful aquascape with only Anubias. However, as with all other plants there are certain conditions you have to take to ensure your Anubias stays in a healthy state.

How to care for Anubias

Many aquarium hobbyists consider Anubias as one of the easiest plants to maintain. It is not demanding at all and requires little light and nutrients. Follow these guidelines to ensure your Anubias receives the utmost care:

Optimum temperature, pH and nutrient levels are important factors. Do thorough research to find out which levels are the best according to the tank size and population of fish and other plants.

Anubias don’t fancy living in the limelight, they thrive better behind the scenes. Do not expose them to too much light. They might grow a tad faster but there is a dark side to too much light. Soon enough, algae will grow on the leaves and destroy your plant.

If you have substrate like gravel or sand on the floor of your fish tank, do not bury the roots, otherwise, the rhizome will rot and kill the entire plant. Instead, anchor it to a rock or driftwood and then place it on the substrate. The roots will soon anchor themselves around the rock.

Keep the tank clean to avoid the accumulation of pollutants. Besides harming the fish, these pollutants will affect the health of the plant.

Common diseases and treatment

Unfortunately, these aquarium beauties are susceptible to disease like any other plants. The most common symptoms are:

1. Rotting roots and a softened rhizome

A healthy rhizome is green and firm, whereas a diseased one becomes mushy and develops a white, yellow, brown, or black discoloration. If the disease is left to advance, a foul odor will soon emanate from the rotting rhizome.

Treatment: The best way to deal with this problem is to cut away the infected part of the rhizome. This gives the rest of the plant a chance to grow healthy.

2. Melting leaves

There are two major causes, one being that an infected rhizome will infect the stem and soon will reach the leaves and cause them to rot. Secondly, if your Anubias was grown emersed and then you submerge it, the leaves will start to rot and melt due to this sudden change in their environment.

Treatment: You can slightly tug at the infected leaves and pull them off the parent plant or cut them off at the base.

3. Algae growth

Algae grows on the plant when it is exposed to too much light. It is also caused by adding too much nutrients into the water.

Treatment: Reduce the amount of light or move it to a slightly shaded area in the tank. As for the nutrients, stop adding too much, give the plants only what they need.

Frequently asked questions

How to propagate Anubias?

Propagation is the process of creating new plants. In the case of Anubias, rhizome division method is used. Remove the plant from the water and pat it dry. Using a clean pair of scissors or a knife, cut off at the rhizome. Ensure that the cut pieces have at least three leaves and some roots. Do not divide the parent plant into too many pieces, otherwise, the poor plant will be left struggling to survive. Tie these pieces onto a rock or driftwood and return to the water.

Can Anubias grow out of water?

Absolutely yes. Anubias is a highly adaptable plant and will grow submerged, emersed, or out of water as long as you give it time to adapt to its new environment. If you are growing it completely out of water, make sure the roots are buried in a moist substrate while the rhizome remains visible.

How to grow Anubias fast

With only a few leaves to show each year, Anubias grows pretty slow. You can use these methods to accelerate its growth:

Does Anubias need CO2

Anubias is not a demanding plant at all. It does well even without adding carbon dioxide into the tank. The carbon dioxide breathed out by the fish is sufficient for it. It has however been observed that at high light and high CO2, Anubias grows fast as compared to medium light and high CO2.

How to attach Anubias to rock

Remove the plant from the water and pat it dry. Select a part of the rhizome and tie it to the rock using fishing thread or a rubber band. Don’t tie too tight. You can also stick it using superglue by applying the gel on the rhizome, sticking it onto the rock, and holding it for a few seconds. Return it into the water. The roots will soon anchor themselves around the rock.

Can Anubias grow in sand?

When you are using sand as a substrate, it is not advisable to bury the roots in the sand. Tie the rhizome onto a rock. This rock can then be placed on the sand.

How to trim Anubias

Since Anubias grows slowly, there is not much trimming involved. You only do it once in a while when you want to make it look neat.

If the roots have grown too long, trim them with a sharp knife to get a clean look. As for the leaves, watch out for older leaves and pull them off gently at the base. New ones will emerge after a while. In the case of old or overpopulated plants, the stem is cut at about two inches from the rhizome.
