If you’re in a hurry and eager to find out the best low light aquarium plant. Then we would recommend the Anubias Barteri plant to be the best.
Plants are an essential component of aquariums. Not only do they have their notable aesthetic benefits, but they’re also known for improving the quality of water in your tank. However, whether you are a beginner or an experienced aquarist, you should be aware that most plants need light to thrive. While high amounts of light may be beneficial in enhancing plant coloration and increased growth rates; high light aquarium plants are harder to maintain, thanks to the conducive environment they create for an algae bloom.
This is why I believe low light aquarium plants to be the ideal choice, as they require less maintenance and thrive in most environments. In this guide, I will highlight the important things to know about aquarium plants, with a review of what I believe to be the ten best low light aquarium plants.
What are the different types of aquarium plants?
Not every aquarium plant will be fit for your fish tank. Aquarium plants come in different types which vary in size, shape, color and maintenance needs. Below we have divided the various types of aquarium plants into the following three groups:
Unlike other types of aquarium plants, floating plants don’t have a rooting in the substrate (the material at the bottom of the tank). These plants function well when floating on the water surface, on which their leaves and flowers grow. Examples of floating plants include Duckweed and Hornwort.
Rosette plants are famous for their leafy structures and shortened stems. They can be used in an aquarium as a stand-alone plant or in groups. Examples of rosette plants include Anubias and Amazon Sword.
Ferns and Mosses
Ferns and mosses have become very popular in the world of fish keeping, especially among breeders. This is because they thrive in low light, as well as providing an excellent cover for fry (baby fish) in the tank.
What are the benefits of low light aquarium plants?
The benefits of low light aquarium plants are plenty; they include the following;
Prevention of algae spread
The formation of algae in your aquarium will not only create an unclean environment but can also suffocate your fish. Low light aquarium plants consume nutrients that algae depend on for growth, thus preventing the bloom of algae in your aquarium.
I find an aquarium without plants can appear incomplete. They not only give the aquarium a plush and natural look, but they also give it a personality that enhances the appearance of your tank.
Reducing stress levels
Various factors can contribute to your fish getting stressed, which sometimes can be fatal. Adding live plants to your aquarium will go a long way in calming down stressed fish. Naturally, fish thrive well when around a natural ecosystem, which is what low light aquarium plants seek to create.
Reduction of ammonia circulation
Waste such as excrement from the fish will result in the circulation of ammonia in the aquarium. Ammonia is hazardous, and if not controlled, can lead to the death of your fish. Aquarium plants’ biggest benefit is that they will produce oxygen and absorb the carbon dioxide and ammonia that fish generate.
Food for the fish
What is the difference between Column feeders and Root feeders?
Root feeders are plants that consume essential nutrients via their roots. These plants require a rich substrate layer for deep rooting. Without deep rooting, they will not take up enough nutrients, which can result in the plants decaying.
Column feeders, on the other hand, absorb nutrients through modified stems known as rhizomes. These plants aren’t rooted as deep in the substrate layer, and they can easily take up nutrients from the water.
How many plants should you have for an aquarium?
The number of plants to have in an aquarium depends on the size and number of fish you intend to have. While some fish may live well in a crowded space, some species will require sufficient space for survival; which is why your aquarium shouldn’t be congested with plants. Fishkeeping experts recommend having plants covering 20% – 30% of the surface or front of the aquarium.
Is the natural light sufficient for aquarium plants?
Theoretically, natural light is sufficient for the growth and survival of aquarium plants. However, insufficient light or too much light if not maintained correctly can be problematic for the plants. This is because aquariums encompass a small ecosystem for the plants, and any changes in lighting can result in adverse effects. Too much sunlight can cause an algae bloom. On the other hand, too little light will inhibit photosynthesis, which may eventually lead to the death of the plants. Having regulated lighting is, therefore, fundamental if you plan to sustain a healthy aquarium.
