Community Aquariums
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.
Goldfish Aquariums
The bright colors of goldfish make for an attractive display and often are a first choice for many beginners. A combination of Ryunkins and Lion heads, pearlscaper plastic plants, black gravel and grey and white granite stones represents a combination which would attractively contrast with the vivid colors of goldfish.
African Cichlid Aquariums
The most common African Cichlid aquariums consist of either Lake Tanganyika or Lake Malawi cichlids. It is suggested not to mix these two groups together due to character and dietary differences. Both types of setups would generally consist of large quantities of rockwork combined with a fine substrate, gravel or sand. These fish dig, so careful attention should be paid to setting up rocks, to avoid possible collapses. Plastic plants can be used or live plants such as species of Vallisneria or Anubias can be attempted.
Planted Aquariums
This type of aquarium features emphasis on plants and limited fish populations. An example of a plant tank could feature a backdrop of large groupings of faster growing species, such as species of Hygrophila, Limnophila, Rotala, Vallisneria, with an Echinodorus species in the middle and groupings of Cyptocorynes in the foreground. The gravel would consist of 2 to 5mm diameter at an average depth of 3 inches. Other décor is limited due to the space requirement of the plants and is usually limited to a piece or two of driftwood. Typical choices for fish could be smaller tetras or Rasboras and some angelfish. It would also be suggested in this type of setup to include some algae controlling species of fish, such as Siamese Flying Fox. Lighting, CO2 injection, fertilization, and attention to appropriate filtration media are important details as well even though its obvious that a planted aquarium is much more easy than any other.
