General freshwater community aquariums are a common introduction to the aquatic hobby. Fish are usually the main focus, with emphasis on color and hardiness. Aquatic plants often play a secondary role.

It is recommended to select fish and plants that thrive in similar pH and water hardness values. For example, a livebearer community tank containing guppies, swordtails and platies will do well with plants such as Vallisneria Spiralis and Hygrophila Difformis. These fish and plant species enjoy well lit, slightly hard, alkaline conditions.

2 Watts of light per gallon of water is required for proper fish presentation and good plant growth.
