Aquarium plants are a common sight in freshwater tanks. Their bright green colors are gorgeous and offer a unique backdrop against which the vibrant shadings of the fish stand out and may be displayed to their fullest advantage.
In addition to their aesthetic function, aquarium plants also help with the oxygenation of the water, making it a vital addition to the air pump. Fishes and other aquarium life forms may hide in or behind them according to how big they are.
Another important aspect of aquarium plants is the temperature regulation within the tank. While it is true that the temperature fluctuations a tank may weather are only minuscule, the plants do have the power to shade fish from direct light.
In such instances they not only become hiding places for the fish, but the darker leaves also protect them from the damage of direct sun or lamplight. This kind of protection is particularly apropos in cases where the light in the dome of the tropical fish aquarium is too strong for the fish that leave beneath.
Aquarium Plants have become so popular, that some hobbyists forgo the introduction of fish to a tank and instead simply keep the plants. This has the added benefit of not needing to worry about food and also such frequent water changes, although the tank still requires regular cleaning to remain largely algae free. It is important to remember that in this instance the overcrowding of a tank with plants may be its own undoing, and moderation is the key to beautiful plant survival.
