Aquarium plants are a common sight in freshwater tanks. The bright green colors are beautiful and provide a special backdrop where the striking shadings of the fish are emphasized and can be seen at their best.
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 benefit of having aquarium plants is the temperature regulation inside the tank. Even though the temperature changes in a fish tank are very small, the plants do have the beneficial ability to shade fish from direct light.
They aren't just useful as hideout places for the fish in your tank, but they also serve to help protect their scales from the damaging effects of direct natural or artificial light. This protection is appropriate when light in the dome of the tank is too strong for the fish living in it.
The popularity of aquarium plants have led some to not keep fish at all and just create water gardens in their aquariums. 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.
