Cory's are small, peaceful catfish which are ideal for the community aquarium. The commonly available species are generally hardy and easy to breed.
• Albino/Bronze cory
• Peppered corydoras
Rainbowfish are colourful and active shoaling fish, which are often overlooked as community fish, probably partly because the juveniles seen in the fish store are not showing their impressive adult colouration. Dwarf species are suitable for smaller tanks.
These fish, popularly known as plecos, are an extremely docile fish. Active during the night, they will feed along with your snail. Smaller specimens may latch on to your snail, but there is no danger.
This common species of fish is a good community fish and are hardy. These species include Platy’s, Guppy’s, and Swordtail’s.
Barbs and Rasboras
These are an active and colourful addition to any community tank. Not all are peaceful, and some grow quite large, but the species listed opposite are ideal for the general community tank.
• Cherry barb
• Golden barb
• Five-banded barb
Hardy, active shoaling fish with no special requirements.
Unlike many of the larger cichlids, the dwarf cichlids from South America, and some from Africa, are generally peaceful, and only become territorial when a pair are spawning. Most only grow to around 2" (5cm) long.
The loach species make an interesting addition to the community aquarium. The species listed below are sociable towards other fish and best kept in groups. Note that some other species of loach, includingt the clown loach, can be aggressive, especially toward apple snails.
• Clown loach (AGGRESSIVE!)
• Pakistan loach
• Zebra/Candy-stripe loach
Though small, they can be aggressive and aren't recommended companions of other slow moving fish such as Angelfish. Body color is dark red, with several blue vertical bands running along the fish. The upper body and head are spotted in black.
Relatively undemanding fish. They are primarily nocturnal, but once well-settled in an aquarium and given retreats, they will venture out and be seen looking for food. Although peaceful towards most fish, individuals may be territorial toward one another, and very small fish are regarded as food.
