In addition to it, we will provide the top 30 low-light aquarium plants that you may buy as per your requirements and suitability.

 

What are low-light aquarium plants?

Low-light aquarium plants are those plants that survive in the minimum light of the aquarium. These plants are said to be easy plants, as no special maintenance is required for them, and they bloom in the aquarium’s low light. These plants are also used to give a beautiful and lively appearance to an aquarium that otherwise looks dull and boring. Here, low light refers to the fluorescent grow light of 1.5 watts per gallon. This much light is enough for the growth of plants that are hardy by nature. If the plants do not receive proper nutrition, they will eventually die.

We all know that the generation of algae is an underlying problem in aquariums. In this regard, these aquatic plants give balance to the growth of algae and keep it at the bay of the aquarium. Now, you must be wondering how plants can help reduce algae. Well, plants and algae feed on the same nutrients in the aquarium; therefore, plants end up absorbing more nutrients leaving less for the algae. As a result, it reduces the growth of algae.

Now, let’s have a look at the top 30 low-light plants to keep in your aquarium; they will not only make your fish tank look beautiful but also help in eradicating algae.

Benefits of keeping low light aquarium plants:

If you are planning to get low-light aquarium plants for your tank, then let us tell you that there are many benefits of having them. Some of the significant benefits we have listed below.

Water oxygenation:

Aquatic plants come of great help in keeping the aquatic animals healthy. The low-light aquarium plants inhale a considerable amount of carbon dioxide released by the marine animals, and in turn, release fresh oxygen for the fishes and other aquatic animals.

 

Natural habitat:

Aquatic plants, especially the low-light ones, serve as an excellent natural habitat for fishes. Your tiny fishes use these plants to hide and play around, which gives them an ocean-like feeling, thereby keeping them happy. So, keeping a low-light aquarium plant is a good decision to recreate a natural habitat for your favorite fishes.

 

Stability of the surface:

These plants are beneficial for maintaining the stability of the substrate in the aquarium. If there are no aquatic plants, then the filter outflow or marine animals might end up destroying the substrate.

 

Algae removal:

The low-light aquatic plants are also a great help in maintaining the natural balance in the aquarium. These plants help prevent the overgrowth of algae in the fish tank, thereby keeping the tank clean and tidy, and maintaining an optimum condition for the survival of the water animals.

 

Sanctuary:

These low-light aquarium plants help the aquatic animals to feel comfortable. The fishes breed and lay eggs, hiding them behind or beneath these plants, which resemble their natural habitat. Also, these low-light plants protect some of the fishes by providing them with a place to hide from the aggressive species in the aquarium.

 

Things to consider before buying low-light aquarium plants:

Low-light aquarium plants help in keeping your aquarium tidy as well as look mesmerizing. However, before buying these plants, there are a few things that one should always consider. Let’s have a look at those factors.

Fish type present in your tank:

The growth and development of the low-light aquarium plant heavily depend on which fish species you have kept in your aquarium. Some plant-eating fishes might end up destroying the plant entirely. Therefore, make sure if you have a plant-eating fish or invertebrate in your aquarium, then you must pair them with plants like Barteri and Anubias Nana that taste bitter. This characteristic will help them save the plant from getting uprooted and destroyed.

 

Light intensity in the tank:

The lighting of the aquarium is another crucial thing to consider. If the lighting in your aquarium is quite bright, then low-light plants would not be able to survive inside. It is essential to adjust the light according to the plant’s needs; otherwise, it will die.

 

Plant feed:

It is vital to know about all the plants thoroughly before you buy them. What feed your plants need is essential for you to know. If you are not fertilizing the plants properly or keeping them away from any other nutrient that they require, then you are killing them slowly.

 

Plant density ensuring carbon-oxygen ratio:

Like all other living organisms, plants also need carbon, which they get from the carbon dioxide released by the fishes. If your aquarium is full of aquatic plants, then the competition for carbon dioxide is on a hike. So, make sure to maintain the balance of carbon and oxygen in the water for the plants to grow in better conditions.
