This broad classification of aquarium generally refers to a mix of fish and plants originating from different geographical areas, with emphasis placed on color and hardiness. This type of aquarium can be very successful if it follows basic rules for compatibility of its inhabitants with respect to temperature, water chemistry, aquarium size, and character.

For example, various species of gouramis, tetras, and rasboras could be combined with a selection of hardy aquatic plants such as Hygrophila difformis, Hygrophila polysperma,and Vallisneria spiralis. A piece or two of root wood and some smooth pebbles would complete the decor, along with gravel at a 2 to 3 inch depth and a diameter of 2 to 5 mm.
