Why are green plants put in an aquarium?

Benefits for the aquarium environment:

* Oxygen production: Plants release oxygen during photosynthesis, which is essential for the fish and other organisms in the tank.

* Waste removal: Plants absorb nitrates and phosphates, which are waste products from fish and food. This helps to keep the water clean and prevent algae growth.

* Water purification: Plants can help to filter the water and remove harmful substances.

* Natural filtration: Plants create a natural filtration system by providing a surface area for beneficial bacteria to grow, which further helps to break down waste.

* Stability: Plants help to stabilize the pH and temperature of the water.

Benefits for the inhabitants:

* Hiding places: Plants provide hiding places for shy or timid fish, reducing stress.

* Spawning sites: Some fish use plants as spawning sites.

* Natural enrichment: Plants add visual interest and a more natural environment for the fish.

Aesthetic reasons:

* Visual appeal: Plants add beauty and color to the aquarium.

* Creating a natural look: They help to create a more natural and relaxing environment.

Important considerations:

* Choosing the right plants: Not all plants are suitable for every aquarium. Factors to consider include the size of the tank, the water parameters, and the fish that live in it.

* Maintenance: Plants require regular maintenance, including trimming and fertilizing.

* Light: Most aquarium plants need adequate light to thrive. This often means using artificial aquarium lighting.

Overall, green plants can be beneficial to the aquarium environment, the fish, and the aesthetics. They are a valuable addition to many aquariums, but it is important to choose the right plants and provide them with proper care.
