Anubias Congensis: Basic Information

Anubias congensis is native to Africa’s tropical regions, where it grows along streams, rivers and marshes. It is a flowering plant that thrives when the rhizome is attached to a hard surface, like wood or stones.

They require low to medium light and can benefit from fertilization on a regular basis. CO2 is not required, but it can promote faster growth and stronger leaves. Because it is a slow grower, the leaves are prone to algae growth if exposed to bright light. Propagation is simple: Simply cut or pull apart rhizomes to be replanted.

This plant is very appealing with its lush, long-lasting green leaves and strong root structure. Anubias are a hardy, low-maintenance plant that can be used as a foreground, midground, or background plant. Anubias is ideal for anyone involved in the fish-keeping hobby.

Anubias Congensis Care

Anubias are an excellent choice for a beginner, especially if you are new to plants or are attempting to maintain a planted aquarium. Another reason they are easy to keep is that they do not need to be planted in the substrate.

They can be rewarding for another reason — aside from their ability to survive even in poor aquarium conditions — in that they can produce flowers underwater with low lighting.

You can solve all the problems associated with a non-planted aquarium by using live aquarium plants and you can also improve the performance of your aeration, filtration, food, and algae control systems. You can make a difference in the lives of your fish.

Anubias Congensis: Potential Problems

Anubias congensis care is similar to that of other Anubias plants. It works best in the middle ground and looks best in low to moderate lighting. Excessive lighting, unfortunately, can cause unsightly, pesky algae growth on its leaves.

This algae growth, however, can be easily controlled in an aquarium with a healthy population of shrimp (especially Amano shrimp) that will constantly graze on the algae without harming the Anubias plant itself.

To help prevent algae from growing on your anubias, do the following:

  • Plant it in a shady spot.
  • Set your lights to a timer to shorten the period of exposure.
  • Maintain regular water changes to reduce nutrient levels in the water.
  • In case of algae infestation, performing a spot treatment with Seachem Flourish Excel is the most effective way to combat algae on Anubias leaves.

Apart from algae, also some “wood-eating” Panaque of the Plecos genus may chew holes in Anubias congensis leaves, but most herbivorous animals will not harm it.

Anubias Congensis: Height

This African aquatic plant reaches a medium height, and thus should be considered a plant for the medium or foreground, depending on dimensions of your tank. Anubias congensis height reaches upto 3.9 5.4 inches and requires an average quantity of light. Even in the best condition, the Anubias congensis growth rate will be very slow.

The main distinguishing feature of this variety of Anubias is the slightly longer leaf shape compared to the other species. If your tank isn’t well-lit, don’t worry: Anubias congensis will not suffer from it. If anything, it will grow slower in a dimmer tank.

It is one of the tallest Anubias blade-like species. Anubias congensis is an excellent plant for the mid or background of your tank, with a beautiful dark lime green colour and thick sword-like leaves.

Anubias Congensis: Propagation

Being a rhizome plant, it is very easy to propagate Anubias congensis. Using a very sharp knife, cut the rhizome into smaller sections. When you do this, you may lose some of the original leaves, but they will be replaced by new growth once the pieces have been re-planted.

When the mother plant is mature enough for propagation, the rhizome will develop small roots along its length indicating that, when the rhizome is divided, the roots will develop quickly.

Remove the mother plant from the tank with care and cut the rhizome into equal-sized pieces. These should then be returned to the tank, taking care not to completely bury the rhizome in the substrate; rotting will occur quickly if the rhizome is submerged in the soil medium.

At least half of the rhizome should be visible, and the small roots should be facing downwards. This may seem obvious to most of you, but it is always something to keep in mind. After a few weeks, you should notice new growth, which indicates that the propagation was successful.

Anubias Congensis: Planting

Anubias congensis plantingPlanting Anubias congensis is most effective when the rhizome is attached to driftwood or rockwork. It can be planted in the substrate, but the rhizome must not be completely buried, or it will rot and recede. This plant can also be grown in terrariums, paludariums and aquariums as an immersed plant.

The roots of this species will grow and wrap around objects if planted in the substrate or attached to decorations. This allows you to put color wherever you want. It is not only decorative, but it also serves as a habitat for fish.

The leaves provide your aquatic pets an escape from other noisy fish and create shaded areas for those who want to get out of the sun. Because it is a planted species, you can choose the location of each plant, which aids in aquascaping the tank. Unlike floating plants that drift around, you can choose the location of each specimen of Anubias congensis.

Tank Requirements

Water parameters

When it comes to water parameters, anubias are fairly laid back. They grow best in a neutral pH zone of 7.0, but they can grow in nearly any pH parameter. Their ideal pH range is between 6.5 and 7.8. They grow well in both soft and acidic water.

Anubias thrive in warmer water temperatures ranging from 72 to 78 degrees Fahrenheit. But, in terms of Anubias temperatures, they simply require water that is warmer than 68 degrees Fahrenheit and not scorching hot.

Tank Size

Depending on the variety of your Anubias, they can thrive in a small to large aquarium.

Dwarf varieties are best suited for small fish tanks, whereas some, such as the gigantea, can only be grown in large tanks. Look for the specific characteristics of whichever variety you choose to understand what your plants’ exact needs are.

The most important thing to remember, given the tank size, is that most Anubias varieties require planting in a minimum depth of 12 inches of water.

Things To Look While Buying Anubias Congensis

Anubias congensis benefitsAnubias congensis leaves are dark green: If the colour fades or patches of yellow and brown appear, the plant is not healthy. Experts advise against purchasing such a plant.
